As wet steam is heated further, the droplets evaporate, and at a high enough temperature (which depends on the pressure) all of the water evaporates and the system is in vapour–liquid equilibrium. [5] When steam has reached this equilibrium point, it is referred to as saturated steam.
An enthalpy–entropy chart, also known as the H–S chart or Mollier diagram, plots the total heat against entropy, [1] describing the enthalpy of a thermodynamic system. [2] A typical chart covers a pressure range of 0.01–1000 bar , and temperatures up to 800 degrees Celsius . [ 3 ]
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 ...
The pressure on a pressure-temperature diagram (such as the water phase diagram shown above) is the partial pressure of the substance in question. A phase diagram in physical chemistry , engineering , mineralogy , and materials science is a type of chart used to show conditions (pressure, temperature, etc.) at which thermodynamically distinct ...

Description: Blue lines indicate vapor quality, mass percentage in the saturated mixture that is in gas phase . Black lines indicate pressure in pounds per square inch . Grey lines indicate specific volume in square feet per pound-mass of steam
The differences between a sauna and a steam room are twofold: temperature and humidity, says Mindy Pelz, M.D., holistic health and women’s health expert. “A sauna is usually about 150 to 200 ...
Although the relation between vapor pressure and temperature is non-linear, the chart uses a logarithmic vertical axis to produce slightly curved lines, so one chart can graph many liquids. A nearly straight line is obtained when the logarithm of the vapor pressure is plotted against 1/(T + 230) [8] where T is the temperature in degrees Celsius ...
