What will likely happen to a helium balloon taken outside on a cold winter day?

• The balloon will be smaller, because the air inside the balloon will cool and expand.

• The balloon will be smaller, because the air inside the balloon will cool and contract.

• The balloon will be larger, because the air inside the balloon will warm and expand.

• The balloon will be larger, because the air inside the balloon will warm and contract.

• be easy to open and shut.

• will expand making it difficult to open and shut.

• will not have a problem because it is a strong metal

• will contract making it difficult to open and shut.

Why do objects tend to expand when they are heated?

• Heat transferred to the object causes potential energy to increase and spread apart

• Heat transferred is not moved to the new object at all

• Heat transferred to the object causes kinetic energy of particles to increase and spread apart

• Radiation is needed

The speeds of two bumper cars decrease as the collide and slow down. What happens to the temperature of the bumpers due to the force of friction

• Both bumpers cool down

• Both bumpers warm up

• One bumper cools while the other warms up

• Both bumpers remain the same temperature
