It belongs to the second law of thermodynamics and says that why we cannot cool the room by leaving your refrigerator door open.
00:08
So suppose this is our refrigerator and this refrigerator is taking heat from this tl that is lower temperature reservoir and releasing heat to the room which is comparatively at higher temperature.
00:22
And this is a refrigerator.
00:24
And on the refrigerator we do some work using compressor and heat is taken up.
00:30
Out from the lower temperature and it is delivered to the room that is at higher temperature.
00:35
So now if we close open the gate of the room, the refrigerator, open the gate of the refrigerator then the refrigerator will start taking heat from the room.
00:50
And as we are doing some work using compression.
00:54
So compression will do make more work because the temperature is higher.
01:00
Of the room than the compartment of the refrigerator.
01:03
So by doing more work, the more heat will be transferred...
