Question

Expansion of liquids on heating is different from solids since the expansion of liquids is

• A. much more than solids because molecular spacing in them is less
• B. much more than solids because molecular spacing in them is more
• C. much less than solids because molecular spacing in them is more.
• D. much less than solids because molecular spacing in them is less

Answer 1

The correct option is B much more than solids because molecular spacing in them is more

When a liquid and a solid are both heated to the same temperature, the rate of expansion are not the same.Liquids expand volumetrically on heating and is roughly 10 times moire than solids.
The reason why liquids expand more than solids is due to the intermolecular spacing. In liquids the molecules are loosely packed when compared to solids.
