water to gas
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
there is no particular point which gas changes to liquid, because all substances have different points where gas changes to liquid. Water vapor changes to liquid at 100 degrees Celsius
The name for liquid when it changes into gas is called evaporation.
The process in which a solid changes to a liquid is called melting.
When a substance changes from liquid to solid is called freezing.
They are physical changes.
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
When water is boiled it changes from liquid to a gas.
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
These are changes of phase and physical phenomenons: - solid to liquid: melting - gas to liquid: liquefaction (or condensation)
When water freezes it changes from a liquid to a solid. When water boils or evaporates it changes from a liquid to a gas.
A substance changes from a solid to a liquid at its melting point
