Gertrude is observing liquids at a birthday party. Some are sweet, some are hot, and some are sticky. If she could look at the particles of the liquids, which statement would be true?

• The particles are far apart and moving fast, with no shape.

• The particles may touch but they can flow past each other.

• The particles are in close contact and cannot move from their places.

• The particles have no arrangement.

Herbie notices that a spill on the kitchen floor was gone the next morning. The best description of what happened to the spill is

• It evaporated

• It sublimated.

• It boiled.

• It froze.

Herbie makes a graph of the temperature of a solid as he heats it. What shape will the graph have?

• A diagonal line that starts low and keeps going up the whole way.

• A diagonal line that starts low, has a flat portion, then goes up again.

How are boiling and evaporating different?

• They both are processes that change a liquid to a gas.

• Boiling requires heat to be added so the particles rapidly change to a gas.

• Evaporating requires heat to be added so the particles rapidly change to a gas.
