Thermal Energy Chapter 1

What is the relationship between temperature and kinetic energy of molecules in an object?

• As temperature increases, the kinetic energy of molecules decreases

• As temperature increases, the kinetic energy of molecules also increases

• As temperature decreases, the kinetic energy of molecules increases

• There is no relationship between the two

Which is an example of energy being converted?

• Scientists use thermal energy from volcanoes to help power homes using electrical energy

• Thermal energy from a boiling pot of water is making the air above it warmer

• Air conditioner takes hot air out of the room and replaces it with cold air
