a physical change :)
With the help of some physical and chemical processes matter changes its state. Like using heating , cooling etc we can change the state of matter,
the matter always stays the same, expansion and contraction just means the matter is becoming more/less spread out from one another. A change in the state of matter is turning from solid-liquid-gas. The amount of matter always stays the same!
When matter undergoes a chemical change, the composition of the matter changes. When matter undergoes a physical change, composition of the matter remains the same.
This is called a change in phase or a phase transition. It occurs when a substance transitions from one of the states of matter (solid, liquid, gas) to another due to changes in temperature or pressure.
When a liquid changes to a gas, that can be done by means of a slow process called evaporation, or a fast process called boiling.
Energy is lost or gained.
The process is called a phase change or a change of state. This occurs when matter transitions from one physical state, such as solid, liquid, or gas, to another state due to changes in temperature or pressure.
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.

solidifying - its a changing state of matter
The state of matter changes from a liquid to a gas. (But the one word answer that the assignment is looking for is vaporization.)
Condensation is a physical process in which a gas changes into a liquid state. It is not a distinct state of matter but rather a transition from a gas to a liquid at a particular temperature and pressure.
A change of state occurs when a substance changes from one of the four states of matter to another. The four states of matter are solid, liquid, gas, and plasma. A common example would be an ice cube melting from solid to liquid. Another example would be when dry ice (frozen carbon dioxide) goes from solid directly to gas in a process called sublimation.
Matter changes state because of pressure and temperature.
if u are talking about a solid to a gas then it is called sublimination
