Question

why do state of matter change?​

Answer 1

Answer:

Most matter changes because of heat energy. Changes in pressure can change matter, too. When matter is heated enough, the molecules move faster and with greater energy. If enough heat is added, a solid can become liquid and a liquid can become gas.

Answer 2

Explanation:

The state of matter change due to change in energy of constituent atom

e.g.

Solid - on increasing energy converted into liquid because due to energy atom can move a little

On further increasing the energy liquid converted into gaseous state because high kinetic energy the atom can move far off
