Question

Thermal expansion of liquids is more than of solids.

• A. True
• B. False

Answer 1

The correct option is A True

1. Solids have a fixed shape and fixed volume therefore it expands in all direction.
2. Solids have all three; linear, area and volume expansion.
3. In liquid, it has only a fixed volume, Therefore liquid has only volume expansion.
4. When a liquid is heated in a flask having a capillary tube, it is observed that the liquid first fall to a certain level in the tube.
5. Then it starts rising to a great level, this indicates that the liquid expands more than the solid.

Thus, the given statement is true.
