Question

The extent of expansion is different in different solids.

• A. True
• B. False

Answer 1

The correct option is A True

1. The property of the substance due to which it expands on heating is called thermal expansion.
2. The expansion of solid depends upon the nature of the material.
3. Some materials expand more on heating while some expand less.
4. The expansion of a solid also depends upon temperature.
5. If we increase the temperature of solids, the internal energy of the molecules increases and so is the internal molecular vibration.
6. Hence, there is a linear expansion of the solid.
7. Hence, The extent of expansion is different in different solids.
   Thus the given statement is correct.
