TE 2.5: Explaining Changes in Temperature

Objective: KWBAT communicate how energy transfers between things and when energy stops transferring between things, by creating and explaining models that represent Riverdale School.

Part 1: Warm Up

3

Categorize both of the images to their correct category!
Remember that the definition of equilibrium is “a balanced state at which a system is stable, such as when two or more samples are at the same temperature.”

At Equilibrium
Not at Equilibrium

2

Which TWO system samples are NOT at equilibrium?

Sample A

Sample B

Sample C

Sample D

1

Why are those systems not at equilibrium?
System _ and System __ are not at equilibrium because....

Part 2: Averages and Equilibrium

null

1

The average temperature of molecules in diagram 1 is…

10

30

3

1

The average temperature of molecules in diagram 2 is...

6

3

18

1

By the end of energy transfer, all the molecules now have the same _____.
(select all that apply)
Hint: When both systems are at equilibrium, what happens??

kinetic energy

temperature

molecule movement

1

Which of the following is NOT true of the final diagram above (in purple)?

The molecules in A and B are moving at the same speed

The temperature of A and B are equal

The molecules in A and B are no longer moving

The system is in equilibrium

Think about what happens to the molecules as soon as energy stops transferring.

Molecule speed for both systems will be the same!
