Based on what you know about the way molecules move in HOT liquids, why does the liquid in the thermometer go UP when heated?

• the molecules speed up and spread apart taking up more space

• the molecules slow down and get closer together taking up less space

• the molecules slow down and spread apart

• the molecules speed up and get closer together

Based on what you know about the way molecules move in COLD liquids, why does the liquid in a thermometer go DOWN when cooled?

• the molecules move faster and spread out and take up more space

• the molecules move slower and get closer together and take up less space

• the molecules move faster and get closer

• the molecules move slower and spread out

What happened to the atoms in the heated metal ball so that it didn't fit through the ring?

• the atoms moved faster and spread apart causing the ball to expand

• the atoms moved slower and got closer together causing the ball to shrink

• the atoms moved faster and got closer together

• the atoms moved slower and got further apart
