# States of matter, melting and boiling points

> Matter is solid, liquid or gas; the melting point and boiling point are the temperatures at which a substance changes state; stronger forces between particles mean higher values.

> [ar-EG] الـ matter بتبقى solid أو liquid أو gas. الـ melting point والـ boiling point هما درجات الحرارة اللي عندها المادة بتغيّر حالتها. ولما الـ forces بين الـ particles تكون أقوى، القيم دي بتطلع أعلى.
