Matter: Properties and Change!
Correct Answer,Keywords, and Definitions
- The correct answer is gold because gold is a pure substance, and the only pure substance out af all four answers
- Pure Substance//a sample of matter w/both definite and constant composition w/distinct chemical properties
- pure substance = element = atom = uncuttable
Pure Substances vs Mixtures
An ice cube is put into a heated pan. What will most likely happen to the molecules in the ice as the ice is heated?
- The molecules will begin to mover slower
- The molecules will begin to move slower
- The molecules will begin to increase in density
- The molecules will begin to condense in the air
Correct Answer, Keywords, and Definitions
- (Ice cube) Cold, (heated) Hot, Most Likely, Molecules (slower/faster)
- The correct answer is the molecules will begin to move faster because as the ice cube gets hotter (solid to liquid to gas) it starts to form a liquid and eventually turns to a gas making the molecules move faster

What happens to water molecules during the boiling process?
- They move faster and move farther apart as the absorb heat
- They move faster and remain close together as they absorb heat
- They move more slowly but move farther apart as they lose heat
- They move move faster and farther apart as they lose heat
Correct Answer, Keywords, and Definitions
- Boiling Process
- Kinetic energy is the energy of motion (basically movement)
- The first option (A) is correct because heat provides kinetic energy
