P-V plots for two gases during adiabatic process are shown in the figure. Plots I and 2 should correspond respectively to

Four curves A, B, C and D are drawn in the adjoining figure for a given amount of gas. The curves which represent adiabatic and isothermal changes are

In pressure-volume diagram given below, the isochoric, isothermal, and isobaric parts respectively, are

The P-V diagram of a system undergoing thermodynamic transformation is shown in figure. The work done on the system in going from A → B → C is 50 J and 20 cal heat is given to the system. The change in internal energy between A and C is

An ideal gas is taken through the cycle A → B → C → A, as shown in the figure. If the net heat supplied to the gas in the cycle is 5 J, the work done by the gas in the process C → A is

In the following indicator diagram, the net amount of work done will be

A cyclic process for 1. mole of an ideal gas is shown in figure in the V-T diagram. The work done in AB, BC and CA respectively

The temperature-entropy diagram of a reversible engine cycle is given in the figure. Its efficiency is

A cyclic process ABCA is shown in the V-T diagram. Process on the P-V diagram is
