Question

Change of state takes place at a fixed temperature. Give reason.​

Answer 1

Explanation:

Energy is always involved in changes of state. Matter either loses or absorbs energy when it changes from one state to another. For example, when matter changes from a liquid to a solid, it loses energy. The opposite happens when matter changes from a solid to a liquid. For a solid to change to a liquid, matter must absorb energy from its surroundings. The amount of energy in matter can be measured with a thermometer. That’s because a thermometer measures temperature, and temperature is the average kinetic energy of the particles of matter.
