Question

How does heating and cooling affect the movement of particles?

Answer 1

Explanation:

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

Answer 2

Answer:

On increasing temperature, the particles gets energised, hence they start moving very fast. Therefore, heating increases the movement of particles. On the other hand, when the temperature is decreased, the particles becomes 'lazy' or less energetic. Therefore, cooling decreases the movement of particles
