100

What happens to the molecules in an object when its temperature increases?

the energy of the molecules increases

100

When hot toast is placed on a plate and the plate's energy increases, this happens to the toast's energy.

the toast's energy decreases

100

In the space shuttle example, this layer has higher molecular energy before they touch.

the outer layer

100

When the same amount of energy transfers to objects of different sizes, this one will be cooler.

the larger object

100

This incorrect concept suggests that "cold" is a type of energy that transfers between objects.

cold energy

200

This is the difference between molecules in hot soup versus cold soup.

molecules in hot soup move faster than molecules in cold soup

200

This type of energy transfers from hot objects to cooler objects when they touch.

kinetic energy

200

When comparing paint buckets, the one with molecular energy of 18 versus 12, this one is hotter.

the bucket with energy level 18

200

This is why a larger object becomes cooler when receiving the same energy transfer as a smaller object.

the energy spreads out over more molecules

200

This incorrect idea suggests that temperature increase is caused by these combining with object molecules.

heat molecules

300

What happens to the energy of molecules when a computer cools down to prevent breaking?

the energy of the molecules decreases

300

When two objects of different temperatures touch, energy transfers until they reach this.

the same temperature (thermal equilibrium)

300

In the pipe example, the front pipe with energy 100 compared to the back pipe with energy 75

the front pipe is hotter than the back pipe

300

In the gear example, after energy transfer, this gear will be cooler and why.

the larger bottom gear will be cooler because energy spreads over more molecules

300

The incorrect belief that when objects reach thermal equilibrium, the cooler one always reaches this specific energy level.

the same energy as the hotter object

400

What happens to candle wax molecules when the temperature decreases after being blown out?

the energy of the molecules decreases

400

When iced tea is poured into a glass and the glass's energy decreases, this happens to the iced tea's energy

the iced tea's energy increases

400

When Bree's potato was in the campfire and Rico's wasn't, this describes the molecular difference.

molecules in Bree's potato move faster than Rico's

400

In the chef's pan example, this bottom pan will be cooler after stacking.

the larger bottom pan

400

This false idea suggests there's no difference between molecules of the same substance at different temperatures.

molecules are identical regardless of temperature

500

This describes what happens to rice molecules when left on the stove and temperature increases.

the energy of the molecules in the rice increases

500

The final temperature of two touching objects will always be this compared to their starting temperatures.

in between their starting temperatures

500

In the chair example, the bottom chair with energy 35 compared to the top chair with energy 20.

the bottom chair is hotter than the top chair

500

In the laptop example, this laptop will be cooler after touching, and the reason involves molecular distribution.

Odessa's laptop will be cooler because energy spreads out over more molecules

500

The incorrect notion that molecules in cold objects do this compared to molecules in hot objects.

don't move at all
