It is a reversible process- Melting of ice

Classify the following as reversible of irreversible changes: Melting of wax.

A sample of an ideal gas is expanded 1 m^(3) to 3 m^(3) in a reversible process for which P=KV^(2) , with K=6 "bar"//m^(6). What is work done by the gas (in kJ) ?

For a reversible process at equilibrium, the change in entropy may be expressed as

2 mole of an ideal monoatomic gas undergoes a reversible process for which PV^(2)=C . The gas is expanded from initial volume of 1 L to final volume of 3 L starting from initial temperature of 300 K. Find DeltaH for the process :
