Answer:

✰Answer✰

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

Explanation:

1) Expansion:

When heat is added to any substance, the particles gain energy and vibrates(with more speed) or vigorously about their fixed positions, forcing each other further apart.

Order of expansion Gas>Liquid>Solid

2) Increase in temperature:

When heated there is increase in kinetic energy and particles move at higher speed. Since temperature is a measure of average Kinetic Energy, the temperature increases.

3) Change in state:

When there is phase change of solid to liquid and liquid to gas, temperature remains constant but there is absorbing of heat, heat absorbed is used to separate particles and there is no rise in temperature.
