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.

What happens to molecules when their kinetic energy decreases?

• They move slower.

• They move faster.

• They get heavier.

• It depends on the type of molecules.

Jose's go cart is made of steel. When are the steel molecules in his bicycle moving?

The aluminum molecules are . . .

• only moving when Jamil is riding his bicycle.

• only moving when Jamil is not riding his bicycle.

• always moving.

• never moving.

When molecules flow around each other, they are in this phase

• solid
• liquid
• gas
• plasma

If you have a liquid that changes to a gas, explain it's freedom of movement in both phases.

• molecules move away from each other, then around each other
• molecules move in place, then around each other
• molecules move around each other, then away from each other
• molecules move around each other, then in place
