A student has a glass of water and a block of ice. Both the water in the glass and the block of ice are made up of the same number of molecules. The average speed of the molecules of the water is greater than the average speed of the molecules of the block of ice. Which has more thermal energy and why?

• The ice has more thermal energy because it is a solid and the water is a liquid.

• The water has more thermal energy because the ice has no thermal energy, but the water does.

• The water has more thermal energy because the molecules of the water are moving faster than the molecules of the ice.

• The water and the ice have the same amount of thermal energy because they are different forms of the same substance.

Consider the following situations: Situation 1: A waterfall is used to turn a wheel. Situation 2: A wood fire in a fireplace is used to heat a room. Is energy being transferred in either of these situations?

• Energy is transferred in both situations.

• Energy is NOT transferred in either situation.

• Energy is transferred when a waterfall is used to turn a wheel, but energy is NOT transferred when a fire in a fireplace is used to heat a room.

• Energy is transferred when a fire in a fireplace is used to heat a room, but energy is NOT transferred when a waterfall is used to turn a wheel.

A girl is riding her skateboard down a hill. She speeds up as she goes down the hill, and the wheels get a little warmer. What energy transformations happen while she is going down the hill?

• Kinetic energy is transformed into potential energy and thermal energy.

• Potential energy is transformed into kinetic energy and thermal energy.

• Potential energy is transformed only into kinetic energy.

• No energy transformations are involved while she is going down the hill.

A man is driving a car. He slows down to stop at a stop sign. Speed = 30 miles per hour Speed = 15 miles per hour Speed=0 miles per hour When does the car have the most kinetic energy?

• When the car's speed is 30 miles per hour

• When the car's speed is 15 miles per hour

• When the car's speed is 0 miles per hour

• The car's motion energy is the same the whole time.
