Phase Change Amplify in Spanish

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.

A car mechanic had a sealed bucket containing a substance in the gas phase. She left the bucket outside over the weekend. When she returned, the substance had changed phase, and the substance was in the liquid phase. What happened to the molecules of this substance?

• Before the mechanic left, the molecules were moving away from each other. When she returned, they were moving around each other.

• Before the mechanic left, the molecules were moving around each other. When she returned, they were moving in place.

• Before the mechanic left, the molecules were moving around each other. When she returned, they were moving away from each other.

• Before the mechanic left, the molecules were moving in place. When she returned, they were moving around each other.

A student left a sealed jar of water outside her home. Water can be a solid, liquid, or gas. When she put it outside, the water was a liquid. Twelve hours later, the water had changed phase and was a soldi. What happened to the water molecules?

• Before the student left, the molecules were moving in place. After, the molecules were moving around each other.

• Before the student left, the molecules were moving around each other. After, the molecules were moving away from each other.

• Before the student left, the molecules were moving around each other. After, the molecules were moving in place.

• Before the student left, the molecules were moving away from each other. After, the molecules were moving around each other.
