The energy contained in atoms and molecules makes them vibrate and this vibration produces heat. Matter expands with heat. In an iceberg (solid matter), for example, the molecules absorb radiant energy from the sun and vibrate even more. Their temperature increases, they expand and form water (liquid matter). The molecules in the water vibrate until they evaporate and go up in the air (gaseous matter). When the temperature decreases, their vibration slows down and they condense into drops that fall as rain. Water is a liquid composed of two gases: oxygen and hydrogen.
