      Although steam is considered as a perfect gas on account of It being a mixture of dry steam (gas) and moisture (water), it possesses properties like those of gases : namely, pressure, volume, temperature, internal energy, enthalpy and entropy. But the pressure, volume and temperature of steam as a vapour are not connected by any simple relationship
