When a real gas is compressed from low pressure to a higher pressure, its temperature increases. This is because the compression work done on the gas is converted into internal energy, which increases the temperature of the gas. The enthalpy change for this process is negative, because the heat lost by the gas is less than the work done on the gas. The entropy change for this process is also negative, because the gas becomes more ordered as it is compressed.
