Temperature & Kinetic Energy

Multiple Choice

Which explanation best describes what happens to the metal ball from step 1 to step 3 in the demonstration?

• The particles in the ball gained kinetic energy when the temperature increased, and this caused them to spread out and increase the size of the ball.

• The particles in the ball gained kinetic energy when the temperature increased, and this caused each particle to increase in size, so the ball expanded.

• The particles in the ball lost kinetic energy to the air when the temperature increased, which caused the particles to spread out and make the ball larger.

• The heat added particles to the ball, which made the ball increase in size.

Which of the following are true about the relationship between mass, temperature, and thermal energy?

• An object with more mass at the same temperature has more thermal energy.

• An object with higher temperature but less mass can have less thermal energy than a cooler, larger object.

When comparing two systems, what does it mean if both have greater thermal energy and greater average kinetic energy?

Multiple Choice

Which of the following statements about thermal expansion is correct?

• When an object gets warmer, its particles move faster and spread out, causing the object to expand.

• When an object gets colder, its particles move faster and spread out, causing the object to expand.

• When an object gets warmer, its particles slow down and get closer together, causing the object to contract.

• Thermal expansion only occurs in liquids.
