n moles of an ideal gas undergoes a process A → B as shown in the figure. Maximum temperature of the gas during the process is

The pressure of an ideal gas varies with volume as P = αV, where α is a constant. One mole of the gas is allowed to undergo expansion such that its volume becomes `m` times its initial volume. The work done by the gas in the process is

`n` moles of an ideal gas undergoes a process A ® B as shown in the figure. The maximum temperature of the gas during the process will be :

The ratio of work done by an ideal monoatomic gas to the heat supplied to it in an isobaric process is:

An ideal monatomic gas with pressure P, volume V and temperature T is expanded isothermally to a volume 2V and a final pressure P_i. If the same gas is expanded adiabatically to a volume 2V, the final pressure is P_a. The P_a/P_i ratio is
