Identify the arrows that represent the process of cooling

Arrows B, C and E

Explanation:

Solid state : In this state, the molecules are arranged in regular and repeating pattern. The molecules are closely packed that means they are fixed and vibrate in place but they can not move from one place to another.

Liquid state : In this state, the molecules are present in random and irregular pattern. The molecules are closely packed but they can move from one place to another.

Gaseous state : In this state, the molecules are present in irregular pattern. The molecules are not closely packed and they can move freely from one place to another and spread out.

Thus Solid is changed to liquid on heating and liquid gets back to solid on cooling.

Liquid changes to gaseous state on heating and gases gets back to liquid on cooling.

Solid is changed to gas on heating and gases get back to solid on cooling.
