Question

The melting point of gallium is ${30}^{\circ }\text{C}$. Then its freezing point will be ____${}^{\circ }\text{C}$.

• A. 30

Answer 1

The correct option is A 30
The highest temperature at which a substance remains a solid and the temperature at which it starts becoming liquid would almost be the same. So, we often consider that for a particular substance, the freezing point as well as the melting point are almost the same.

In the case of gallium, since the melting point is ${30}^{\circ }\text{C}$, its freezing point will also be the same.
