The 1st Law of Thermodynamics states that the heat added to a system is equal to the increase in internal energy and the external work done by the system.
system
Decrease entropy
False
Heat added = (increase in internal energy) + (external work done by the system)
True
Decreases (Temperature decreases)
True
Law of Conservation of Energy
