Question

Why do liquids expand more than solids on heating?

Answer 1

Liquids are expanding more than the solids on heating because molecules are easily moved than solids.

Explanation:

Thermal expansion of solids:

• In solids, atoms vibrate quicker about their positions which are fixed while on heating. Therefore, the comparative rise in solid size when heated is low.
• Metal tracks on the railway  have tiny gaps so that the tracks grow into these gaps when the sun heats them and do not buckle.

• Liquids expands are expands more than solids because the “bonds between” distinct molecules are less tight. This is the ‘principle’ behind thermometers for liquid-in-glass.

Answer 2

Answer:

Explanation:Liquids have less strong force of attraction so,they expand more than solids
