Changes of state, or of phase as it is also called, are described by a single word, but there is a different word for different changes of state.
Solid to liquid is called melting.
Liquid to solid is called freezing.
Liquid to gas is called boiling.
Gas to liquid is called condensing.
Solid to gas is called sublimation.
The state of matter remain unchanged.
no physical change does not change matter
Change of state.
state of matter
The state of matter remain unchanged.
a change in size, shape or the state of matter is a physical change. True for A+.
It can.
States of matter are bulk properties. A single atom does not have any bulk properties, so it has no defined state of matter.
Some changes of physical state are described by a single word, for example, the change from a liquid state to a gaseous state is called boiling, and the change from a liquid state to a solid state is called freezing. There is, however, no single word which means change of physical state in general.
Because melting is a change of state: from solid to liquid.
A change in the state of matter occurs when heat energy is added or removed.
phase change.
