Question

Why do changes in state of matter take place

Answer 1

Answer:

Changing states of matter occur when matter loses or absorbs energy. When a substance absorbs energy the atoms and molecules move more rapidly and this increased kinetic energy pushes particles far enough, that they change form. This energy is usually heat or thermal energy.

Explanation:

Answer 2

Answer:

Matter change its state only when the particles of matter absorb energy. When the particles gain energy then they use to move here and there more rapidly which leads to the chance in state of matter.

Basically when atoms and molecules of the matter get increase in their kinatic energy then they start moving and then the state of matter changes. :-)
