TE 3.1 Thermal Energy is NOT Temperature

KWBAT gather more evidence about energy transfer by actively reading the Amplify article “Thermal Energy is NOT Temperature”, and answer critical thinking questions to prepare for the next lesson.

Part 1: Warm Up

On the left is an image of a small cup of tea. The water inside the teacup is very hot, about 80oC. On the right is an image of a large bathtub. The water inside the bathtub is warm, about 40C.
Question 1

Question 2
2.

Predict: What do you think total kinetic energy means?

Sentence starter:
I think that total kinetic energy means...

Question 3

Elaborate: Explain you answer choice for the question above. Why do you think that object has a greater total kinetic energy?

Sentence starter:
I think that the ______ has a greater total kinetic energy because...

Part 2: Thermal Energy is NOT Temperature

The comparison of the hot tea and the warm bathtub water is similar to the comparisons that you will need to make between the two heating systems for Riverdale School—one system’s reservoir is smaller but hotter, while the other system’s reservoir is larger but not as hot. In order to choose between these systems, you must begin by thinking about which system actually has more total kinetic energy to transfer?

Read the article and answer the questions!

Why does a bowl have more total kinetic energy than a mug?
because the molecules in a mug had energy destroyed
because the bowl was heated up to a higher temperature
because soup in a bowl has more molecules than soup in a mug
Why does the soup in the mug cool down faster?
because the soup in the mug has lower average kinetic energy
because the mug does not have a high total kinetic energy
because the mug was already cooled down to begin with
The bowl has a much higher total kinetic energy because it has a higher temperature.
True
False
How do you calculate the total kinetic energy of something?
you look at how fast its molecules are moving
you cannot calculate the total kinetic energy of something
you add up all of the molecules
When the soup and the air have the same average kinetic energy, that means that they are....
at equilibrium
stable
still transferring energy
creating or destroying energy
Analyze the image: The bowl of soup and the mug have the same ________ but they have different _____________ because of the differing amount of molecules.
average kinetic energy, thermal energy
solar energy, molecules
thermal energy, average kinetic energy
