Question

Which of the following do not undergo significant expansion or contraction with change in their temperature?

• A. Solids
• B. Liquids
• C. Gases
• D. All undergoes the same amount of expansion.

Answer 1

The correct option is A

Solids

Solids do not undergo significant expansion or contraction with the change in their temperature as the atoms are tightly packed in the solids compared to the liquids and gases. The forces of attraction between atoms are very less in liquids and gases as compared to that of solids. Hence, solids undergo minimum expansion or contraction when the temperature is changed.
