1. i read all my notes about the thermodynamics laws and the second one was so interesting? As i found it opposes the first one so how ia that possible. If not just tell me the right thing. 2. I've tried to make a diffenrence between the heat engines and the refrigerator: heat engines absorb heat and transform it( not completely) into work whereas refrigerators transorm work (with some few additional heat) into heat. But the problem is that i'm not conviced about the refrigeratorm, so i want someone else to make me sure.
