An object that has a high temperature has ______________ moving particles. That means the average kinetic energy of the particles is ___________________

• slow, low

• slow, high

• fast, low

• fast, high

Answer explanation

The particles of higher-temperature substances move faster than the particles of lower-temperature substances. Faster particles have more kinetic energy than slower particles.

Look at the image, predict which beaker should have the most thermal energy.

• Left

• Right

• Middle

Answer explanation

The water in the first beaker is at the same temperature as the water in the second beaker, but it has more mass. Therefore, the water in the first beaker has more thermal energy. The water in the second beaker has the same mass as the water in the third beaker, but it has a higher temperature. Therefore, the water in the second beaker has more thermal energy than the water in the third beaker.

When you hear a loud sound, what kind of energy transfer is primarily happening?

• From light to sound energy

• From mechanical to sound energy

• From sound to mechanical energy

• From thermal to sound energy

What happens to the temperature of the water when it reaches its boiling point and begins to vaporize?

• The temperature remains at 100°C until the change of state is complete.

• The temperature continues to rise during the change of state.

• The temperature begins to decrease during the change of state.

Answer explanation

The temperature of a substance does not change while a change of state is occurring. This is shown by the horizontal lines at 0°C and 100°C on the graph.
