Question

What causes expansion in liquids
​

Answer 1

Answer:

Liquids expand for the same reason, but because the bonds between separate molecules are usually less tight they expand more than solids. ... Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid.

Answer 2

Answer:

Expansion and Contraction in Liquids

When liquids are heated, their particles move around more, pushing each other apart slightly, causing the liquid to expand.
