Lily is doing a science experiment with a substance in a sealed jar. At first, the substance’s molecules are moving around each other. What will happen to Lily’s substance if she transfers energy into the substance and causes a phase change? After the phase change, the substance’s molecules will move . . .

faster, and the substance will be a gas.

faster, and the substance will be a liquid.

slower, and the substance will be a solid.

slower, and the substance will be a liquid.

A scientist has a container with a substance inside. At first, the molecules in the substance move away from each other. Later, the molecules move around each other. What change did the scientist observe in the substance?

Before, the substance was a gas. Later, it was a liquid.

Before, the substance was a liquid. Later, it was a solid.

Before, the substance was a liquid. Later, it was a gas.

Before, the substance was a solid. Later, it was a liquid.

A cook had a jar containing a sweet food and a jar containing a sour food. The image above shows the sweet and sour foods. At room temperature, both foods are liquids. The same amount of energy was transferred into both substances. Later, one of the foods had changed phase while the other had not. Which food changed phase, and how did it change?

The sweet food changed because the molecules were able to move fast enough to overcome the attraction between them. Its molecules now move away from each other.

The sweet food changed because the strong attraction between molecules made their movement slower. Its molecules now move around each other.

The sour food changed because the weak attraction between molecules let them move faster. Its molecules now move away from each other.

The sour food changed because the molecules were able to move fast enough to overcome the attraction between them. Its molecules now move in place.

A scientist has two substances that she is testing in her lab: a pink substance and a green substance. At room temperature, both substances are liquids. The scientist transferred the same amount of energy into both substances. She finds only the pink substance changed phase. How is the pink substance different from the green substance? The pink substance has a . . .

weaker attraction between its molecules than the green substance. Its molecules now move away from each other.

weaker attraction between its molecules than the green substance. Its molecules now move in place.

stronger attraction between its molecules than the green substance. Its molecules now move away from each other.

stronger attraction between its molecules than the green substance. Its molecules move around each other.
