Expansion during heating:

Options

  1. Aincreases the weight of a material
  2. Bdecreases density of material
  3. COccurs only in solid
  4. DOccurs at same rate of all liquids and solids

Correct answer

B. decreases density of material

Step-by-step solution

Expansion during heating is the process to change the volume of matter in response to change in temperature. During thermal expansion, the density of substance decreases as its volume increases. Increase in volume-occupying a large space. The atoms of matter are distributed in larger spaces.
