Created by StemPy LabA gas is taken round a cycle of three steps. From A to B its internal energy increases by while it does of work. From B to C its volume stays constant and it gives out of heat. From C back to A it is thermally insulated, so no heat flows. Which statement about the step from C to A is correct?

← A Carnot engine takes in 1000 J of heat from a reservoir at 500 K and gives out heat to the surroundings at 300 K. All the work it does drives a Carnot refrigerator, which takes heat from a cold store at 250 K and gives it out to the same surroundings at 300 K. How much heat does the refrigerator take from the cold store? Give the answer in J.An ideal monatomic gas expands slowly along a path on which PV^(1.2) stays constant. Which statement is correct for this expansion? →
