Difference Between Conduction, Convection, and Radiation

 Difference Between Conduction, Convection, and Radiation (With Table)

The transmission of energy between things of various temperatures is known as heat. The average kinetic energy of the particles in an object is measured by temperature. Kinetic energy is the energy stored in motion. The energy of motion is known as kinetic energy. The energy of motion increases as the temperature rises. 

Conduction, convection, and radiation are the three methods through which heat can be transmitted. In this article, we have distinguished all three forms of heat transfer.

Conduction vs Convection vs Radiation

The main difference between conduction, convection, and radiation is determined by the medium. Conduction is the transmission of heat across objects via direct touch, whereas convection is the transmission of heat across items via the flow of a medium like air or water. Heat is delivered through radiation without any physical contact between objects.

Example of conduction: When we make tea, heat from the stove is transferred to the steel pan due to direct contact, resulting in conduction. Heat energy is transmitted from ironed clothing when they are ironed.

Example of convection: When we heat a pot of water, the water particles at the surface heat up first; we know that heat causes particles to travel faster, therefore these particles move randomly and a relatively empty space is formed. Particles from far locations migrate here to fill the space. Again, these particles require heat energy and go away, and the process repeats itself, resulting in hot water from cold water.

Example of radiation: When boiling water on the stove, heat conducts from the stove to the pot because it is directly in contact. All water particles gain heat as a result of convection. You will feel hot if you raise your hand closer to the pot's side; this is caused by the pot's radiation.

Comparison Table Between Conduction, Convection and Radiation

Parameters of Comparison





Conduction of heat requires the presence of a medium.

For heat transfer by convection, a medium is required.

The use of a medium is not required for radiant heat transmission.


In a vacuum, conduction is not possible.

In a vacuum, convection is not possible.

In a vacuum, radiation can happen.

Effects on medium

The medium particles do not deviate from their average location. They dissipate heat by vibrating around their centre of gravity.

The medium particles leave their average position and migrate upward, transporting heat from the source.

The medium is unaffected in any way.

Direction of heat

Heat can be transferred in any direction.

The only way for heat to be transferred is vertically upward.

Heat is transferred in all directions in a straight line.

Time taken

The process is slow.

The process is faster than conduction.

The process is the fastest and the transfer of heat takes place with the speed of light.

What is Conduction?

The process of heat transfer in which heat is transmitted from one portion of the body at a higher temperature to another area of the body at a lower temperature without the molecules moving from one place to another is known as conduction.

Conduction occurs most commonly in solids as a result of temperature differences. It happens as a result of free electron energy transfer and molecular lattice vibrational energy transmission.

Free electrons are responsible for 70% of heat transfer, whereas vibration is responsible for the remaining 30%.

When one end of a metal rod is heated, the other end eventually becomes heated as well.

What is Convection?

Convection unlike conduction occurs in liquids and gases. It is the transfer of heat through the movement of particles. Warm particles rise, cool particles fill in space below, so this is a circular motion.  

Natural, forced, gravitational, granular, or thermomagnetic convection are all possible classifications.

When we heat a pot of water, the water particles at the surface heat up first; we know that heat causes particles to travel faster, therefore these particles move randomly and a relatively empty space is formed. Particles from far locations migrate here to fill the space. Again, these particles require heat energy and go away, and the process repeats itself, resulting in hot water from cold water.

What is Radiation?

Heat energy can also be transported without the use of particles, allowing it to pass across a vacuum. This occurs when energy is delivered through radiation, specifically infrared wavelengths.

All objects are capable of both absorbing and emitting radiation at the same time. The hotter something is, the more radiation it emits.

This is why putting your hand over a grill, even if you aren't touching it, feels hot. Infrared radiation is emitted by the extremely hot metal and coal, which is absorbed by your hand. When we look at infrared radiation in the context of the electromagnetic spectrum, we can see how it is.

Main Differences Between Conduction, Convection and Radiation

  1. The presence of a medium is required for heat conduction and convection. Radiative heat transfer, on the other hand, does not require the usage of a medium.

  2. Conduction and convection are impossible in a vacuum, but radiation is feasible.

  3. In conduction, heat can be moved in any direction, whereas in convection, heat can only be transferred vertically upward. Radiation is a method of transferring heat in a straight line in all directions.

  4. Conduction is a slow process, whereas convection is quicker than conduction, and the process is the quickest, with heat transfer occurring at the speed of light in case of radiation.

  5. Conduction requires heated solids, while convection necessitates the use of fluids, and radiation necessitates the use of electromagnetic waves as a medium.


Heat is carried via conduction from a hot item or region to a cold object or area, whereas heat is transported by convection through the flow of fluid currents, and heat is transported sans any medium by radiation.

In thermodynamics, the modes of heat transmission, such as conduction, convection, and radiation, are important topics.

Frustration and Depression is at All Time High

Frustration and Depression is at All Time High. How to Overcome from Frustration and Anger and Inspire and Motivate Your Team

As the Covid situation worsens, there is the frustration of being confined to one's home with limited human interaction which is also depressing. Employees are not able to interact with their colleagues, there are no longer the coffee break talks and the team outings which contributed to a happy and social workplace. Along with that the pressure of work from home where employees now have to draw a line by themselves between their personal and professional lives. It is difficult to multitask as the line between work and life becomes blurred in this situation. All these contribute to increasing frustration and decreasing mental health in employees.

When we look at overcoming this and being able to #Inspire and #Motivate the team, the manager should be able to keep their personal frustration at bay while interacting with their subordinates. It would be a good method to make available therapy or #Mental Health helpline ready for the employees whenever needed. This would show the employees that the organization cares for the well-being of its employees. Create a #Positive Work Environment for the employees. This is required because the last thing an employee wants in such a situation is a more stringent and autocratic workplace. Such a change would create a better emotionally healthy employee who will be more motivated to contribute to the organization. Conduct #Informal Meetings to promote healthy conversations about the negative situation and the frustrations the employees are facing. The realization that everyone around them is going through the same situation will ease the frustration experienced by them.

When we look at the manager’s perspective, the manager must be able to access the same provisions given by the organization to make sure they also get to talk about the hardships of leading a team in such a scenario. When anger kicks in #Breathe, it may seem very minimal but very effective. Deep breaths would help calm your system and help you think better and deal with situations in a better manner. 

Another method is #Contemplating how your favorite leader would deal with the situation. Such a scenario building would help in determining an objective and the best way to handle an issue. There would be thinking involved and the instincts that one has when angry is not heeded to. Thus leading to better decisions.

Indian Premier League is a waste of time

Apda Mein Avsar” or “Opportunity in Distress

Indian Premier League is a waste of time 

IPL is a waste of time

Absolutely Yes

They are operating the league for business purposes. Players who shine in the IPL are not doing well for their national team. Whether foreign or Indian players, they use the platform to gain fame. Only chain business players take this as an opportunity to register their name at the national level.

Others are already in the national team, so they play for entertainment.

However, like news channels, the IPL has become a daily soap for men. For most men, there is no such thing as extra play. This is a good time-pass for all small shop owners around the street, which is itself a very big market in addition to fans of the avid service class, who like to watch evening matches with dinner.

In your view this is one of the reasons that IPL has not developed as a football. People who watch football die hard supporters of a club and they only watch those matches. They just keep one track for comfort. Indian league cricket is not yet developed. That's why you feel like its overdoses because you might like to watch all the matches. You want to enjoy cricket as a sport and not as a fan of the team. Once you reach a point, when you have the same feelings for the IPL team that you have for the national Indian cricket team, you do not waste time or waste your interest. And it will be. People will reach that stage, but it will take 40-50 years.

Is the IPL a complete waste of time and ruining our interest on cricket?

Do Indians waste time watching cricket?

Why do people waste their time watching cricket,

What our PM Mr. Narendra Modi has said.

Unique experience of treating severe Kovid epidemics using technology.

इंडियन प्रीमियर लीग एक समय की बर्बादी क्यों आईपीएल समय की बर्बादी है?

बिल्कुल हाँ।

व्यवसाय के उद्देश्य से वे लीग का संचालन कर रहे हैं। आईपीएल में चमकने वाले खिलाड़ी अपनी राष्ट्रीय टीम के लिए अच्छा नहीं कर रहे हैं। चाहे विदेशी हो या भारतीय खिलाड़ी वे प्रसिद्धि पाने के लिए मंच का इस्तेमाल करते हैं। केवल श्रृंखला व्यवसाय खिलाड़ी इसे राष्ट्रीय स्तर पर अपना नाम दर्ज करने के अवसर के रूप में लेते हैं।

अन्य पहले से ही राष्ट्रीय टीम में हैं, इसलिए वे मनोरंजन के लिए खेलते हैं।

हालाँकि, न्यूज़ चैनलों के समान पुरुषों के लिए आईपीएल एक दैनिक साबुन बन गया है। अधिकांश पुरुषों के लिए, अतिरिक्त खेल जैसी कोई चीज नहीं है। यह सड़क के आसपास के सभी छोटे दुकान मालिकों के लिए एक अच्छा टाइम-पास है, जो अपने आप में एवीड सर्विस क्लास के प्रशंसकों के अलावा एक बहुत बड़ा बाजार है, जो शाम के खाने के साथ शाम के मैच देखना पसंद करते हैं।

आपके विचार में यह कारण है कि आईपीएल फुटबॉल के रूप में विकसित नहीं हुआ है। जो लोग फुटबॉल देखते हैं वे एक क्लब के कठिन समर्थक मर जाते हैं और वे केवल उन मैचों को देखते हैं। आराम के लिए वे सिर्फ एक ट्रैक रखते हैं। भारतीय लीग क्रिकेट अभी तक विकसित नहीं हुआ है। यही कारण है कि आप इसके ओवरडोज़ की तरह महसूस करते हैं क्योंकि आप सभी मैच देखना पसंद कर सकते हैं। आप एक खेल के रूप में क्रिकेट का आनंद लेना चाहते हैं न कि टीम के प्रशंसक के रूप में। एक बार जब आप एक बिंदु पर पहुंच जाते हैं, जब आपके पास आईपीएल टीम के लिए वही भावनाएं होती हैं, जो आपके पास राष्ट्रीय भारतीय क्रिकेट टीम के लिए होती हैं, तो आप समय की बर्बादी या अपनी रुचि को बर्बाद नहीं करते। और यह होगा। लोग उस अवस्था में पहुंच जाएंगे, लेकिन इसमें 40-50 साल लगेंगे।

क्या आईपीएल समय की पूरी बर्बादी है और क्रिकेट पर हमारी रुचि को बर्बाद कर रहा है?

क्या भारतीय क्रिकेट देखने में समय बर्बाद करते हैं?

लोग क्रिकेट देखने में अपना समय क्यों बर्बाद करते हैं,

इंडियन प्रीमियर लीग (2021)?

बहुत सारी मनोरंजक चीजें हैं जो पेंटिंग, स्केटिंग, तैराकी, नृत्य, क्राफ्टिंग, आदि जैसे कर सकते हैं।

क्या आईपीएल समय की बर्बादी है?

आईपीएल क्यों समय की बर्बादी है?

मैं अपना समय बर्बाद करने के बजाय अपने जीवन में कुछ उत्पादक या रचनात्मक कर सकता हूं
