One mole of an ideal gas, initially at303.15K(30°C)and1bar, is changed to403.15K(130°C)and10bar by three different mechanically reversible processes:

The gas is first heated at constant volume until its temperature is403.15K( 1 30°C);then it is compressed isothermally until its pressure is10bar.

The gas is first heated at constant pressure until its temperature is403.15K(130°C);then it is compressed isothermally to10bar.

The gas is first compressed isothermally to10bar; then it is heated at constant pressure to403.15K(130°C).
