In an adiabatic process on gas with γ = 1.4, the pressure is increased by 0.5%. The volume decreases by about

The molar heat capacity for the process shown in the figure is

In an isothermal process on an ideal gas, the pressure increases by 0.5%. The volume decreases by about

Two samples A and B are initially kept in the same state. Sample A is expanded through an adiabatic process and sample B through an isothermal process. The final volumes of the samples are the same. The final pressures in A and B are p_A and P_B respectively.

Let T_a and T_b be the final temperatures of the samples A and B respectively in the previous question.
