Which of the following would DECREASE the average kinetic energy of the particles that make up a bowl of soup?

Putting the soup in the refrigerator

Heating the soup up for one minute on the stove

Doubling the amount of soup in the bowl

Imagine you have a large pot water and a small pot of water. To start out, both pots of water have the same temperature, room temperature (20°C ). The larger one would take longer to boil. Why?

Because the larger one has more molecules to transfer the energy through

Because there is more friction between the molecules in large pot of water

Because there is more thermal energy in the small pot of water

Because the average kinetic energy of the particles in the large pot is greater

How do particles lose thermal energy? Think back to what happened to the tennis balls and the food coloring lab.

Particles lose energy when they collide with higher energy particles.

Particles lose energy when they collide with lower energy particles.

Particles lost energy when gravity pulls particles down towards Earth.

Which one of the following would occur if the molecules in substance A were to come into contact with the molecules in substance B?

The temperature of the substance A would increase.

The thermal energy of substance A would increase.

The molecules in substance B would transfer their coldness to the molecules in substance A.

If you were to mix substance A and B together in one container and leave the container out in room temperature air (20°C ), eventually the temperature of the mixed substance would be....

colder than room temperature (less than 20°C)

warmer than room temperature (greater than 20°C)

colder than room temperature then it would warm up again

the same temperature as the air (equal to 20°C)
