Question

Why Substance Are Change Their State When Supplying Heat? ​

Answer 1

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.

Answer 2

${ \large{\underline{ \frak{ \pink{Answer♡}}}}}:$
