Question

A sample of ideal monatomic gas undergoes the process A?B?C?A in the diagram, where the temperature of state A is 240 K.

(a) Calculate how many moles the sample contains.


(b) Find the temperature of state B.

(c) What is the temperature of state C and what is its pressure, PC?


(d) In process A?B how much work W is performed by the gas?


(e) In the same process, how much heat Q flows into the gas?

(f) What is the change in the internal energy ?Eint of the gas, in process A?B?


(g) During process B?C does heat flow into the gas, out of it, or is there no heat flow at all?

Heat flows into the gas.
Heat flows out of the gas.
There is no heat flow.
Impossible to determine.


(h) In a complete cycle A?B?C?A is net work done on the gas, or by the gas? Justify your answer.

Net work is done on the gas.
Net work is done by the gas.
The net work done is zero.
Impossible to determine.
