heat
tempature
Through friction which creates heat it can change the state of matter.
A 'phase' change.
Hydrogen is a gas in normal conditions.
A gas
Change of state.
You change one state of matter to another by heating the matter or cooling it [aka] adding energy or removing the energy
The change from one state of matter to another is called a phase transition.
a chemical change
phase change.
by changing it
No
Matter I think I'm not 100% shure but it say in my book matter in one state often can change to another state by adding or removing thermal energy

change of state is when the different states of matter are changed into one another. states of matter are gas, liquid, plasma and solid.
If water is being split into hydrogen and oxygen then a change of state (phase change) will occur if the water is in liquid form and the hydrogen and oxygen are evolved as gases. If water vapor is being split, then obviously no change of state occurs. Conversely, solid water in the form of ice could be split into hydrogen and oxygen gas, also undergoing a phase change.
