Given

Multiplying both sides by V

We know ideal gas equation

PV=nRT

Where V= volume of gas

R=gas constant=8.31Jmol^-1K^-1

T=temperature

n=number of moles of gas

P=pressure of gas

Here, it is given that number of moles n=1

So, PV=RT. Putting this value of PV in equation 1

According to question V=V_o

The temperature of the gas when V = V₀ is .
