Question

Solid expand the least on heating and gases, the most.

• A. True
• B. False

Answer 1

The correct option is A True

1. Gases expand more than liquids and solids because the molecules of gases are separated from one another by wide spaces.
2. When gas is heated (heat is a form of energy) its molecules began to vibrate fast and as a result, begin to move away from each other.
3. For solids, they expand the least when heated because the molecules are most tightly packed. they keep on vibrating in their fixed position.
4. Hence, solid expands the least on heating and gases, the most.

So, the given statement is true.
