You change one state of matter to another by heating the matter or cooling it [aka] adding energy or removing the energy
adding heat or freezing
In order for a substance to change, a certain temperature or pressure must be reached.
To change a solid into a liquid, you melt it. To change a liquid into a gas, you boil it. To change a gas into a liquid, you condense it. To change a liquid into a solid, you freeze it. Some solids cannot be melted. Complex molecules may break down or burn before they melt e.g. wood, meat.
True. A physical change is a change from one state to another without a change in chemical chemistry.
Phase changes are easy to observe. One state looks different from another. For example, when ice melts, it is quite easy to see.
Change of state.
The change from one state of matter to another is called a phase transition.
phase change.
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
heat
tempature
A change of the temperature or pressure.
We can change gas into plasma by ionisation
yes
A 'phase' change.
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
Through friction which creates heat it can change the state of matter.
