Ph of steam
When steam has reached this equilibrium point, it is referred to as saturated steam. Superheated steam or live steam is steam at a temperature higher than its boiling point for the pressure, which only occurs when all liquid water has evaporated or has been removed from the system. See more Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the See more Agricultural In agriculture, steam is used for soil sterilization to avoid the use of harmful chemical agents and increase soil health.
