The temperature doesn't change
Explanation:
Given that:
[tex]dU=dQ - dW[/tex]
Where
If the gas does no work and doesn't exchange heat with the outside there insn't a variation of the internal energy.
Internal energy is realted to the energy in the molecules, they vibration and theregore the temperature.
So, if there isn't a change in the internal energy you may say that there isn't a change in the temperature.
The increase in the volume is balanced by a decrease of the pression.
