B. Does the matter change mass in a different container?

D. Does the matter change length in a different container?

Mary put the same amount of matter into the three containers. Based on her scientific investigation, how can the matter be classified?

A. It is a liquid because it has the same volume but changes shape.

B. It is a gas because it has the same volume but changes shape.

C. It is a solid because it has the same volume but changes mass.

D. It is a liquid because it has the same volume but changes mass.

On very warm days, Abby noticed that a metal door fits tightly in its frame and is tough to open. On very cold days, however, Abby noticed the door opens easily. Which choice best explains these differences.

temperature differences effect the molecular energy of atoms in the metal and they 'slow down' and move closer together or 'speed up' and move farther apart

changing temperatures cause atoms in the metal to become larger or smaller

cold temperatures cause atoms in the metal to merge together and warm daily temperatures cause atoms in the metal to split apart and become gas

the door freezes on cold days and is opens freely on warm days

What happens to the arrangement of particles as thermal energy is removed from a substance?

The particles get closer together.

The particles get farther apart.
