The image above shows information about two different substances in sealed containers. At room temperature, both substances are liquids. A scientist transfers the same amount of energy into both substances. One substance changes phase, but the other does not. Which chemical changed phase, and why did it change?
Substance A changed phase because its molecules were able to move fast enough to overcome the attraction between them. Its molecules now move away from each other.
Substance A changed phase because the weak attraction between its molecules allowed them to move faster. Its molecules now move away from each other.
Substance B changed phase because the molecules were able to move fast enough to overcome the attraction between them. Its molecules now move away from each other.
Substance B changed phase because the strong attraction between molecules made their movement slower. Its molecules now move in place

A student left a jar of water outside his home. Water can be a solid, liquid, or gas. When he put the jar outside, the water was liquid. Twelve hours later, the water had changed phase and was a gas. What happened to the water molecules?
When the student left the jar outside, the molecules were moving around each other. Later, the molecules were moving in place.
When the student left the jar outside, the molecules were moving away from each other. Later, the molecules were moving around each other
When the student left the jar outside, the molecules were moving in place. Later, the molecules were moving around each other.

Refrigerators are able to transfer energy out of a substance. At first, the substance is a gas. The refrigerator changes the phase of the substance by transferring energy out of it. How does this change affect the substance’s molecules? After the phase change, the molecules move . . .
slower, and they move away from each other
slower, and they move around each other.
faster, and they move around each other.
faster, and they move in place.

Scientists have a container of water. Water can be a solid, liquid, or gas. At first, the water molecules in the container were moving around each other. Later, the water molecules were moving in place. What change did the scientists observe?
At first, the water was a gas. After, it was a liquid.
At first, the water was a solid. After, it was a liquid.
At first, the water was a liquid. After, it was a gas.

An Earth scientist brought an unknown substance from underground back to her lab. The substance was in the gas phase, and was put into a sealed tank as shown above. She slowed down the molecules inside the tank and the substance changed phase. How did she do this, and how did it affect the molecules? She transferred energy . . .
into the substance, and the molecules moved around each other.
into the substance, and the molecules moved away from each other
out of the substance, and the molecules moved around each other.
out of the substance, and the molecules moved in place.

Two different cars, the Model S and Model T, use different substances in their engines. The image above shows the two substances. At room temperature, both substances are liquids. A car mechanic transferred the same amount of energy out of the two containers, but only one substance changed phase. Which car’s substance changed phase, and how did it change?
The Model T’s substance changed phase because the attraction of the molecules was able to overcome their slower movement. Its molecules now move in place.
The Model T’s substance changed phase because the strong attraction between the molecules made their movement slower. Its molecules now move in place.
The Model S’s substance changed phase because the weak attraction between the molecules allowed them to move faster. Its molecules now move around each other.
The Model S’s substance changed phase because the attraction was able to overcome the slower molecules. Its molecules now move away from each other.
