An isolated box is divided into two equal compartments by a partition (see figure). One compartment contains a van der Waals gas while the other compartment is empty. The partition between the two compartments is now removed. After the gas has filled the entire box and equilibrium has been achieved, which of the following statement(s) is (are) correct? 
1
Internal energy of the gas has not changed.
2
Internal energy of the gas has decreased.
3
Temperature of the gas has increased.
4
Temperature of the gas has decreased.

Consider two identical, finite, isolated systems of constant heat capacity at temperatures and ( ). An engine works between them until their temperatures become equal. Taking into account that the work performed by the engine will be maximum ( ) if the process is reversible (equivalently, the entropy change of the entire system is zero), the value of is:
