The diagram represents equal masses of the same substance in three phases.

Compared to the shapes and volumes of the gas and liquid, the solid

• has a definite shape and a definite volume

• has a definite shape and no definite volume

• takes the shape of its container and has a definite volume

• takes the shape of its container and has no definite volume

The diagram represents equal masses of the same substance in three phases

A comparison of the three phases shows that in the sample of the liquid, the atoms have a

• greater force of attraction than the solid and the gas

• greater force of attraction than the gas, only

• weaker force of attraction than the gas, only

• weaker force of attraction than the solid and the gas

The diagram below represents a roller coaster at two positions on the roller coaster track.

Compared to the potential energy of the roller coaster at the top of hill 1, the potential energy of the roller coaster at the top of hill 2 is

• less because the roller coaster is at a lower elevation

• less because the roller coaster is on a more gentle slope

• greater because the roller coaster is at a lower elevation

• greater because the roller coaster is on a more gentle slope

The diagram represents a closed electrical circuit with a switch and two lightbulbs.

In this circuit, one function of the switch is to

• store electrical energy

• produce solar energy

• transform electrical energy into light energy

• complete the circuit so light is produced
