A monoatomic gas at initial pressure 
and initial temperature 
is allowed to expand isothermally until its volume doubles. Now, it is compressed adiabatically back to the initial volume. The final pressure and temperature are:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
After the isothermal expansion, the pressure is 
, and the temperature is 
Now, for the adiabatic process,
And, the final temperature,
