All right, so this problem has to do with thermodynamics.
00:05
Second law has to do with work, heat, and you're given the heat supply to the system.
00:22
By the system, it's 8 ,000 joules.
00:24
Given the mass of ice that you want to melt, and that's 0 .0 .0 .08 kilograms.
00:37
So you want to find the work done, and we know the formula for that, the work done by the engine is the difference between the absolute value of the heat supplied and the heat lost or discarded.
00:55
So we know this, we want to find, we want to find this qc first, and to do that, you have to recall a little concept, which is a specific latent heat of fusion.

That's what this formula here is...
