An ideal gas undergoes four different processes from the same initial state as shown in the figure below. Those processes are adiabatic, isothermal, isobaric and isochoric. The curve which represents the adiabatic process among $1, 2,3$ and $4$ is:

The efficiency of a Carnot engine depends upon

The $P-V$ diagram for an ideal gas in a piston cylinder assembly undergoing a thermodynamic process is shown in the figure. The process is

Two cylinders A and B of equal capacity are connected to each other via a stop cock. A contains an ideal gas at standard temperature and pressure. B is completely evacuated. The entire system is thermally insulated. The stop cock is suddenly opened. The process is:

In which of the following processes, heat is neither absorbed nor released by a system?

A sample of $0.1\text{g}$ of water at ${100}^{\mathrm{ o}}\mathrm{C}$ and normal pressure $\left(1.013\times {10}^5\mathrm{ N}{\mathrm{ m}}^{-2}\right)$ requires $54\text{cal}$ of heat energy to convert to steam at ${100}^{\mathrm{ o}}\mathrm{C}$. If the volume of the steam produced is $167.1\text{cc,}$ the change in internal energy of the sample, is

A monoatomic gas at a pressure $P,$ having a volume $V$ expands isothermally to a volume $2V$ and then adiabatically to a volume $16V.$ The final pressure of the gas is: (take $\gamma =5/3$)

A thermodynamics system undergoes cyclic process $ABCDA$ as shown in Figure. The work done by the system in the cycle is:
