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.
They are physical changes.
The process in which a solid changes to a liquid is called melting.
When water changes from a solid to a liquid, it undergoes melting. When it changes from a liquid to a vapor, it undergoes evaporation. These changes are driven by increases in temperature and energy levels.
The steam when cooled changes back to liquid water
Freezing
it is called condensation when gas turns into a liquid.
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.
A substance changes from a solid to a liquid at its melting point
