# Problem P. 4148. (March 2009)

P. 4148. A sample of ideal gas is taken from state A to state B in two different ways. The two states has the same temperature.

a) First it is compressed adiabatically (AC), and then it is cooled down such that its volume remains constant (CB);

b) First it is heated at constant volume (AD), then it is compressed isobarically (DB).

In which case do we perform less work? At state C or at state D will the temperature of the gas be greater?
