Changes in states of matter
A change of state is a physical change in a matter. They are reversible changes and do
not involve any changes in the chemical makeup of the matter. Common changes of the
state include melting, freezing, sublimation, deposition, condensation, and vaporization.
These changes are shown in the figure given below.
