Open in App
Solution
The correct option is C Adiabatic
The internal energy of the ideal gas decreases by the same amount as the work done by the system.
From the first law of thermodynamics,
change in internal energy = heat exchange + work done
i.e ΔU=q+w
For an adiabatic process q=0
change in internal energy = work done
i.e. it is adiabatic and the decrease in temperature take place.
