increases

decreases

remains the ​

Answer 1

Answer:

Increases is the answer

Answer 2

Explanation:

When a solid is heated, its atoms vibrate faster about their fixed points. ... 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
