MCQ
Expansion during heating
  • A
    Occurs only in solids
  • B
    Increases the weight of a material
  • ✓
    Decreases the density of a material
  • D
    Occurs at the same rate for all liquids and solids
✓

Answer

Correct option: C.
Decreases the density of a material
(c) Solids, liquids and gases all expand on being heated as result density (= mass/volume) decreases.
