Question 1

1.

Which of the following statements is TRUE about particles that are being heated?

The particles will become closer together (thermal contraction)

The particles will lose thermal energy

Question 2

2.

Putting the soup in the refrigerator

Heating the soup up for one minute on the stove

Doubling the amount of soup in the bowl

Question 3

3.

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

Question 4

4.

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.

Question 5

5.

Option 1

Option 2

Option 3

Option 4

Question 6

6.

Substance A has a greater average kinetic energy of its particles but the same amount of thermal energy as substance B.

Substance A has greater thermal energy but the same average kinetic energy of its particles compared to substance B.

Question 7

7.

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.

Question 8

8.

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

Question 9
