C. The volume of a gas decreases when the temperature decreases Lida fills two balloons with the same amount of air. Balloon 1 remains at room temperature. Lida places balloon 2 in a freezer. The following diagram shows that the volume of the balloon in the freezer shrinks. Which statement is a LAW that describes the results of Lida’s balloon experiments? Decreasing the amount of gas decreases its temperature The volume of a gas increases when the temperature decreases The volume of a gas decreases when the temperature decreases Decreasing temperature decreases the volume of a gas because the molecules slow down.
