Liquid to gas, solid to liquid, and liquid to solid
heat and pressure
"The" two changes are wrong. There are lots of different states of matter, and therefore many different possible transitions. The most commonly studied states of matter are solid, liquid, and gas; each of them can change directly to each of the others, for a total of 6 types of change.
I would suggest temperature and pressure.
Two types of changes in matter are physical changes and chemical changes. Physical changes involve a change in appearance, such as a change in shape or state, without forming new substances. Chemical changes involve a rearrangement of atoms to form new substances with different chemical properties.
Physical changeschemical changesYou must understand that matter can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ).Changing physical states is not a chemical change, but a direct result of heat or cold application.
The two types of changes in matter that it goes through is physical change and chemical change... trust me, we are learning this at school.
The study of properties of matter and how it changes is called chemistry.

Changes of pressure or temperature
Chemistry - the study of the properties of matter and how matter changes
Matter can be changed through physical changes, such as melting or freezing, which are temporary and reversible. It can also undergo chemical changes, like burning or rusting, which are permanent and irreversible.
