Answer:
Physical changes
Explanation:
Changes in the state of matter are physical changes.
First, the material is made up of the same components that is was before it changed states.
The physical properties of the material changed, but its chemical composition did not, meaning that is is a physical change.
Answer:
Physical change
Explanation:
Matter can change between phases, so they are reversible physical changes that do not change matter’s chemical composition.
Changes of state are physical changes in matter. They are reversible changes that do not change matter’s chemical makeup or chemical properties. Water, for example, can be a solid (ice), a liquid (drinking water), or a gas (steam). Those are physical changes that don't change the fact that water is always chemically made up of H2O (two hydrogens and one oxygen).
