Question

The density of liquids and gases change with temperature because there is a change in their mass.

• A. True
• B. False

Answer 1

The correct option is B False

1. When a substance is heated its volume increases and so the density decreases.
2. In solids, an increase in volume is negligible and hence a decrease in density too.
3. In liquids and gases, as the temperature increases, volume increases, and therefore density decreases considerably.
4. Mass is independent and the mass of a substance does not change due to a change in temperature.

Hence, the given statement is false.
