[@bonthudevadasu2944]

Sir from sun no medium but my body is heat ok ...but from 🔥 fire my body also heat ther is also no medium..how this is called convection...??? please give me answer I have feel both same pls difference tell us

[@NAJAMACADEMY]

Well, the Sunlight travels in th form of electromagnetic waves. Electromagnetic waves require no medium, because they are made out of oscillations of electric and magnetic field fields. Energy transfer from electric to magnetic field and then from magnetic field to electric field. By this process, energy travels from one place to another through electromagnetic waves or EM waves.
While in convection process, air molecules absorb energy from the flames or candle; they (molecules) become less denser and raise up. When these molecules come in contact with your body, you feel the hotness...
I hope you will understand it.
Thanks

Heat energy transfer from human body to surrounding IS EXAMPLE OF RADIATION
but it can be of Convection
Am I right ??
Plzz make me understand
I have confusion between these two
Now heat from heater during winter is example of radiation ,how??
Plzz make me understand
It can be of Convection???

[@NAJAMACADEMY]

Good questions...
👏👏👏👏
Well, Heat can also transfer from a human body by convection.
For example, if you enter to a cold room, the air particles will absorb heat from your hot body and will rise up...
Secondly, during exhalation the gaseous particles of carbon dioxide absorb heat from your body, and it comes out. Although, it is due to difference in atmospheric pressure that you inhale and exhale, but carbon dioxide molecules absorb heat from the respiratory track and comes out...
2) When you switch on the heater during winter, the surrounding air molecules come in contact with the hot heater and heat transfer from hot heater to the cold molecules of air. As a result, they get lightness and rise up... This is an example of convection.
Secondly, when you keep some cooking pot on a heater, the particles of the cooking pot absorb heat from the heater, this an example of heat transfer by conduction.
I hope it will clear your confusion...
😊😊😊😊😊

[@aimanahmad5924]

@@NAJAMACADEMY Sir ,what I want to ask that in book NCERT (India) I have read that
HEAT FROM BODY to surrounding is EXAMPLE of RADIATION
secondly heat from heater during winter season is an example of Radiation
WE know NCERT Book is authentic ,All Indians read it and it is written by Scholars
So plzz how they say IT IS RADIATION and hence same process of convention done in above two examples
Plzz assist
As convection and radiation have lots of confusions??
Where convection ,where radiation??
