• They have different shapes.

• They have different colors.

• They have constant contact with each other.

A student is looking at a diagram showing magnified views of the particles in four samples.

Which question would best help the student determine which container holds a liquid?

A science teacher heated liquid ethanol for an experiment. When he turned up the temperature, the ethanol quickly disappeared, and a strong aroma filled the room. What happened to the ethanol?

• Heating the particles in the ethanol caused them to react and bond with gases in the air, which carried the liquid ethanol particles around the room.

• Heating the particles in the ethanol removed some of their mass, decreasing their density and causing them to flow across the room as a liquid.

• Heating the particles in the ethanol energized them, and they began to collide within the container until they escaped to fill the room as a gas.

• Heating the particles in the ethanol removed some of their energy, and they began to slow down and condense within the container as a solid.
