• gas

• solid and gas

• liquid

• liquid and solid

Three grams of the same substance in different phases are stored in three different containers. Each container is barely large enough to hold the substance.

Which statement can be known about the behavior of the atoms in each container?

• The atoms in the solid would be moving vigorously around the container.

• The atoms in the liquid would be vibrating in position.

• The atoms in the gas would be moving slowly around the container.

• The atoms in the solid would be vibrating in position.
