At first, the molecules in the substance move away from each other. Later, the molecules move around each other. What change was observed in the substance?

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

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

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

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

Scientists increased the speed of the substance’s molecules and caused a phase change. How did they do this?

• They put the substance outside.

• They transferred energy OUT OF the substance.

• Not enough information given.

• They transferred energy INTO the substance.

The same amount of energy was transferred into two liquids substances. Later, one changed phase while the other had not. Which changed phase, and how did it change?

• The one with STRONGER attraction it is now a SOLID.

• The one with WEAKER attraction it is now a LIQUID.

• The one with WEAKER attraction it is now a GAS.

• The one with STRONGER attraction it is now a gas.

A pull between two molecules that is always the same for a substance

• Kinetic Energy

• Molecular Attraction

• Molecule

• Mixture

You are drinking a cold drink on a hot day when you notice LIQUID water has collected on the can. Which answer BEST explains what PHASE CHANGE has occurred AND how the molecule ARRANGEMENT has changed?

• The PHASE CHANGE that has occurred is CONDENSATION and the molecule ARRANGEMENT has become CLOSER.

• The PHASE CHANGE that has occurred is FREEZING and the molecule ARRANGEMENT has become CLOSER.

• The PHASE CHANGE that has occurred is EVAPORATION and the molecule MOVEMENT has become FASTER.
