Question

The density of a substance decreases on increasing the temperature

• A. True
• B. False

Answer 1

The correct option is A True

1. As we all know, a substance's density is defined as the mass contained in the body per unit volume.
2. If a material's mass remains constant, its density decreases as its volume increases.
3. So, as the temperature rises, the volume of the substance increases, and the density of the substance decreases.
