heat! so hard.
true or false
1.The entropy of a system can never decrease
2.All Carnot engines are reversible
3.It is impossible have a net transfer of heat from a cold reservoir to a warm reservoir
4.A refrigerator lowers the entropy of the volume inside
5.If the temperature of the cold reservoir increases with the temperature of the hot reservoir unchanged, the efficiency of a Carnot engine will increase
6.Adiabatic expansion will lower the temperature of a gas
7.Any process that includes adding heat to an ideal gas will increase the entropy of the gas
8.All Carnot engines are more efficient than all real engines
