Ty had a container of a substance in the gas phase. He left it outside. Upon returning, it was a liquid. What happened?

molecules were moving around each other then moving away from each other

molecules were moving in place then moving around each other

molecules were moving away from each other then moving around each other

molecules were moving around each other then moving in place

JT has a substance moving in place in a closed container. What happens if he transfers heat into the closed container?

molecules move slower and the substance would be a solid

molecules move faster and the substance would be a liquid

molecules move faster and the substance would be a solid

molecules move slower and the substance would be a liquid

15

Two substances were in liquid form and got energy transferred out. Substance 1 changed, but substance 2 didn't. Why?

substance 1 had stronger attraction; molecules now move away from each oth

substance 1 had weaker attraction; molecules now move around each other

substance 1 had weaker attraction; molecules now move in place

substance 1 had stronger attraction; molecules now move in place

15

Which object below has molecules that are moving?

both have moving molecules

the ocean wave

neither has moving molecules

the glass of water

15

What happens to molecules when kinetic energy increases?

they stay the same

they move faster

they move slower

they defy gravity

15

What happens to molecules when their kinetic energy decreases?

they move faster

it would depend on the type of molecule

they move slower

they get heavier

15

I have pink and blue liquid. Both have energy transferred in to them. Only the pink changes phase. Why?

pink has stronger attraction; now the molecules move away from each other

there is not enough information to answer this question

blue has weaker attraction; now the molecules move away in place

pink has weaker attraction; now the molecules move away from each other

15

How does kinetic energy change if molecules move faster?

it would depend on the molecule

it would increase

it would not change

it would decrease

15

Grandma's pan is made of aluminum. When are the molecules in the pan moving?

they are moving when she cools the pan down

they are moving when she heats the pan up

they are never moving

they are always moving

15

Before leaving home, the pool was 21o C. Later, the pool was warmer. What happened to the molecules?

they lost cold molecules

they started moving faster

they became larger

they got closer together

15

Lulu heated up 3 identical containers on a stove and recorded their increase in temperature. What explains the results?

More energy was added to the 100 g sample so it increased more

The same energy was added to all & the increas was proportional to the mass

More energy was added to the 400 g sample because it had more mass

Energy was removed from the 400 g sample to give it a lower temperature

15

Using the pattern shown in the table, what would you expect the temperature increase to be of a 300 g sample?

6 oF

6 o2

12 oF

0 oF
