Question

Equal lengths of different solids expand by equal amounts when heated equally.

• A. True
• B. False

Answer 1

The correct option is B False

1. Different materials expand differently by applying the same amount of heat energy.
2. For example, if we are heating brass and iron at the same temperature, brass will expand more as compared to iron.
3. So the expansion of materials depends on their own properties, and it is not the same for every material at the same temperature.
4. So, equal lengths of different solids expand by different amounts when heated equally.

Hence the given statement is false.
