Question

Density of a substance does not depend upon temperature.

• A. True
• B. False

Answer 1

The correct option is B False

1. When the temperature of a substance increases the molecules of the substance gain energy.
2. The molecules start to move from one place to another.
3. So the volume of the substance increases.
4. $Density=Mass/Volume.$
5. When the volume of a substance increases its density decreases.
6. So when temperature increases the density of a substance decreases.
7. Hence, the density of a substance depends upon temperature.
8. Hence, the given statement is false.
