    (a) Saturated Steam: Saturated steam is a vapour at the temperature corresponding to the boiling point of the liquid at the given pressure. A substance, which is in the vapour state in a confined space and is in contact with some of the same substance in liquid state is always at the same temperature as the liquid and is saturated vapour. Superheated steam is steam at a temperature higher than its vaporization point at the absolute pressure where the temperature is measured.. Superheated steam can therefore cool (lose internal energy) by some amount, resulting in a lowering of its temperature without changing state (i.e., condensing) from a gas, to a mixture of saturated vapor and liquid. This general steam table uses data that covers compressed water, saturated steam, superheated steam, and supercritical water. Both Temperature and Pressure are required input values.. For saturated steam, use the Saturated Steam Table or the Wet Steam Table.
