Question

Boiling causes a cooling effect.

• A. True
• B. False

Answer 1

The correct option is B False

1. Boiling is defined as the process in which all the particles gain the same amount of heat energy when heated.
2. They will start moving faster after gaining energy and will start escaping from the liquid.
3. It starts from the bottom and is a bulk phenomenon.
4. So, boiling doesn’t produce any cooling effect.
5. Instead, evaporation causes cooling because the heat required to convert surface particles of liquid into vapours is taken away from the liquid itself and the liquid cools down.

Therefore, the given statement is false.
