An ideal gas undergoes for different processes from the same initial state (figure). Four processes are adiabatic, isothermal, isobaric and isochoric. Out of 1, 2, 3 and 4 which one is adiabatic ?

A

4

B

3

C

2

D

1

Text Solution

Verified by Experts

The correct Answer is:
C
1 is isochoric (constant volume) 4 is isobaric (constant pressure). Out of curves 2 and 3 since curve 2 is steeper than curve 3, it represents an adiabatic change whereeas curve 3 represent an isothermal change.

One mole of a monatomic ideal gas undergoes four thermodynamic processes as shown schematically in the -diagram below. Among these four processes, one is isobaric, one is isochoric, one is isothermal and one is adiabatic. Match the processes mentioned in List-1 with the corresponding statements in List-II.
