Kinetic Energy and Temperature Quiz

Which of the following explains how someone could increase the average kinetic energy of particles within a glass of water?

• Increase the amount of water in the glass, because increasing the amount of a substance increases the kinetic energy of the particles.

• Add ice into the water, because when a solid and a liquid mix, the kinetic energy of particles increases.

• Decrease the amount of water in the glass, because decreasing the amount of a substance concentrates the kinetic energy.

• Heat the water in a microwave, because as temperature increases, the kinetic energy of particles increases.

What would you expect to happen to the gas inside a sealed container when the temperature drops, and why?

• The particles would spread out more because decreasing the temperature causes the particles to have more kinetic energy.

• The particles would spread out more because decreasing the temperature causes the particles to have less kinetic energy.

• The particles would move faster because decreasing the temperature causes the particles to have more kinetic energy.

• The particles would move more slowly because decreasing the temperature causes the particles to have less kinetic energy.

Peter is investigating how thermal energy is transferred when he takes food out of the refrigerator. Which statement describes how he could collect data to explain this and what the expected result would be?

• Measure how long it takes the food to reach the same temperature as the interior of the refrigerator. The food will likely gain thermal energy from the cold refrigerator and decrease in temperature until it is the same temperature as the refrigerator.

• Measure the temperature of the refrigerator and the air, and time how long the food is out of the refrigerator for. The cold food will likely gain thermal energy from the warmer air and increase in temperature until it is a little warmer than the air.

• After taking the food out of the refrigerator, measure the temperature of the food at even time intervals. The cold food will likely gain thermal energy from the warmer air and increase in temperature until it is the same temperature as the air.

• Measure the temperature in the food when it is taken out of the refrigerator at various time intervals. The cold food will likely lose thermal energy to the warmer air and increase in temperature until it is the same temperature as the air.

Arthur is investigating how energy is transferred when his bowl of soup cools down. He measures the temperature of the soup near the surface and also at the bottom of the bowl. Over the course of the 5 minutes, the soup near the __________ lost more thermal energy. The particles of soup near the surface have _____ kinetic energy than the particles near the bottom. If thermal energy transfers from the bottom of the soup towards the surface, it is transferred through the process of ________.

• bottom; more; convection

• surface; more; conduction

• bottom; less; convection

• bottom; more; conduction

• surface; less; convection
