Question

Expansion during heating

  1. Occurs only in solid
  2. Increases the weight of the material
  3. Decreases the density of the material
  4. Occurs at the same rate for all liquids and solids

Answer:

Option C: Decreases the density of the material

Detailed Solution:

The correct answer is “Decreases the density of the material”.

Solids, liquids and gases all expand on being heated. As the result of this, density (= mass/volume) decreases.
