2 thoughts on “Why does a liquid expand on heating and contracts when cooled, explain what happens at molecular level?”
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.
