Therefore, it is more convenient to use Table 21.1(a) when temperature is given and Table 21.1(b) when pressure is given. In Table 21.1(a) these properties are listed with reference to saturation temperature and in Table 21.1(b) with reference to saturation pressure.
In steam tables, extensive properties at saturated liquid and at saturated vapor for 1 kg of liquid/vapor are given as shown in Table 21.1(a) and Table 21.1(b).
Extensive properties at saturated liquid and saturated vapor state
