Why does a balloon take up less space when it is cold?

• The particles move faster pushing outward with more force.

• As the energy is destroyed the amount of particles decrease in number.

• Temperature is a measure of the size of particles, so as temperature decrease, the particles contract.

• The particles move slower pushing with less force.
