2003Bb5. One mole of an ideal gas is taken around the cycle `A→B→C→A` as shown on the PV diagram above.
a. Calculate the temperature of the gas at point `A`.
b. Calculate the net work done on the gas during one complete cycle.
c. i. Is heat added to or removed from the gas during one complete cycle?
`\_\_\_` added to the gas `\_\_\_` removed from the gas
ii. Calculate the heat added to or removed from the gas during one complete cycle.
d. After one complete cycle, is the internal energy of the gas greater, less, or the same as before?
`\_\_\_` greater `\_\_\_` less `\_\_\_` the same
Justify your answer.
e. After one complete cycle, is the entropy of the gas greater, less, or the same as before?
`\_\_\_` greater `\_\_\_` less `\_\_\_` the same
