Which would have more thermal energy, a small cube of Ice at zero Celsius or a large cube of ice at zero Celsius?

• The large ice cube because it has more particles than the small ice cube

• The small cube of ice because it will melt faster than the large ice cube

• Neither, they are cold so they do not have thermal energy

• both have the same thermal energy because they are both at zero Celsius.

Which sample has molecules with more average kinetic energy ?

• Sample B, because it has more molecules

• Sample A because it has faster moving molecules

• Sample A because it has yellow molecules

• Sample B because it has brown molecules

Which sample has the higher temperature?

• Sample B because it has more thermal energy and more molecules

• Sample B because the molecules are brown

• Sample A because the molecules are moving faster and have more average kinetic energy

• Sample A because yellow is such a hot color

If you brought sample A and B close together , in what direction would heat be transferred?

• From sample A to sample B

• From sample B to sample A

• Heat would not be transferred.

• sample A and sample B would both transfer heat to each other.

In this example, explain the movement of thermal energy in the glass.

• Heat is moving from the lemonade to the glass

• Heat is moving from the lemonade to the ice

• Cold is moving from the ice to the lemonade

• Cold is moving from the ice to the glass

Louis has two sets of two gears (Set A and Set B) that he is using to build two different machines. He has all the gears laying out separately, as shown in the diagram above. Then he puts the gears into the machines so that the gears in Set A are touching each other and the gears in Set B are touching each other. Use the information in the diagram to answer the question. After the gears have been touching for a while, which of the two bottom gears will be cooler, and why?

• The smaller bottom gear will be cooler than the larger bottom gear, because less energy has to transfer for the molecules to reach the same temperature as the molecules of the top gear.

• The larger bottom gear will be cooler than the smaller bottom gear, because the energy that transferred to it was spread out over more molecules.

• The larger bottom gear will be cooler than the smaller bottom gear. It started with more total energy, so less energy had to transfer for both gears in Set B to reach the same total energy.

• Both gears will be the same temperature, because both of the top gears had the same amount of energy to transfer and the molecules in the bottom gears start with the same energy.

Why does the transfer of energy between two colliding things stop?

• Molecules stop transferring energy when colliding systems reach equilibrium

• When the two non-colliding things get equally hot molecules make energy

• Molecules make more kinetic energy until it is balanced

• The molecules of a system destroy energy when the system is balanced

Your family orders a pizza from Dominoes during CoVid19, the driver left the bag open. The pizza is cold. What happened?

• The energy in the molecules of the pizza decreased

• The pizza lost heat molecules

• The cold energy in the molecules of the pizza increased

• The energy in the molecules of the pizza increased
