First of all, we know that there are three types of, like three modes of heat transfer.
00:06
First is conduction, conduction, second is convection, and third is radiation.
00:18
Radiation is that type of heat transfer, which is like for which energy is transfer in terms of photons or in terms of em waves, electromagnetic waves.
00:28
Okay.
00:30
Like when you are near, like when you are near, say, like, like, for what.
00:37
For the part c, the warmth you feel sitting near a fire.
00:41
So when you are near to a fire, it's just releasing energy in terms of em waves.
00:48
Photones are releasing.
00:49
Okay.
00:50
So for part c, the mode of heat transfer is radiation.
00:56
Convection is that type of heat transfer in which heat is transferred from 1 .7 point a to point b through a medium due to the motion of medium itself...
