Kinetic Energy is the energy of a particle or an object as in motion. 

When placed in hot water…

• More kinetic energy builds up because of the temperature. 

• Hot temperature makes the particles move faster and collide faster, which also generates more kinetic energy. 

• It expands the volume of the balloon. 

• It is a closed system so the air particles push into the balloon outward. 

When placed in cold water…

• Less kinetic energy builds up because of the temperature. 

• Cold temperatures make the particles move slower and collide less, which also decreases the kinetic energy amount. 

• It contracts, not compresses because there’s no external force. It contracts from the decrease of temperature. 

• It is a closed system so the air particles suck in the air down to the bottom of the bottle.
