Published on: August 13, 2026

Answer Q.(i), Q.(ii) and Q.(iii) by appropriately matching the information given in the three columns of the following table.

An ideal gas is undergoing a cyclic thermodynamic process in different ways as shown in the corresponding P -V diagrams in column 3 of the table. Consider only the path from state 1 to 2. W denotes the corresponding work done on the system. The equations and plots in the table have standard notations as used in thermodynamic processes. Here is the ratio of heat capacities at constant pressure and constant volume. The number of moles in the gas is n

The correct answer is:
CHECK THE SOLUTION.

(i)

The process must be isobaric.

(ii)

The correct combination is for isochoric process.

(iii)

The process must be adiabatic, which is used in Laplace correction over Newton's law for sound speed in air.
