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.

Look at the image. Compare the beaker in the middle with the one on the right. Which should have more thermal energy?

• Middle

• Right

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.

Determine whether the objects in the description have the same temperature, the same amount of thermal energy, or both.

A large pot of boiling water and a small pot of boiling water.

• Same temperature

• Same thermal energy

• Both are the same

Answer explanation

Water boils at a specific temperature, but different amounts of boiling water have different amounts of thermal energy.

Determine whether the objects in the description have the same temperature, the same amount of thermal energy, or both.

1 cup of refrigerated milk poured into a tall glass and 1 cup of refrigerated milk poured into a short glass.

• Same temperature

• Same thermal energy

• Both are the same

Answer explanation

The two cups of milk came from the refrigerator, so they have the same temperature. They also have the same amount of matter, so they have the same amount of thermal energy.
