Remarks

・Postulate 1:Volume of saturated vapor has a much higher value than one of liquid.Therefore volume of liquid can be ignored.
・Postulate 2:Vapor will be considered as ideal gas.
・Postulate 3:Latent heat will stay constant with temperature.
・Temperature(K):T
・Latent heat:L
・Vapor pressure(kPa):P0(at T0(K))
・Gas constant:R
