It would depend on how the water was heated. Tankless Coil, there should be a valve on the side of the coil, that has a knob on top, that is your mixing valve and should be used to adjust water temp. Indirect Hot Water Tank, it is connected to boiler through piping, but does not have it's own burner...should have a box on it, (aquastat), that will adjust the temp of your hot water, likewise with a Direct Fired Hot Water Tank, which is the same as mentioned above, but with it's own oil burner.
When water is heated, it can turn into steam, which is essentially water vapor.
Water heated will turn into water vapor. Even when it's not heated, evaporation is a process that occurs at all temperature for water, so water vapor can always form.
Evaporation.
When water is heated at extremely high temperatures.
Vapour, which raises up to the sky and becomes part of a cloud.
Vapor, its chemical elements do not change.
An average is 130 f. If you have small children, turn it down to 120f at the regulator if gas, or the knob on the lower element if electric.
When water is heated, the molecules gain energy and move faster, causing them to break free from the liquid phase and turn into gas. This process is called evaporation. As more water molecules evaporate, the overall level of the liquid water decreases.
If a hydro-carbon is burnt it will make heat, CO2 and water however if a hydro-carbon is heated it will just expand into its surroundings
When water in the ocean is heated by the sun it turns into water vapour and evaporates, however it leaves the salt behind as it is made of separate molecules.
turn your temp down to 65 it will be cold just let her run
They melt..> they melt and turn back to water.
