Sonja and Jeremy performed several experiments to show how changes in temperature affected the volume of an inflated balloon. They made sure the pressure stayed the same. They also showed the effects of pressure on volume if temperature stayed the same. They organized their information in this table. Experiment Volume Pressure Temperature
A Increases Stays the same Increases
B Decreases Stays the same Decreases
C Increases Decreases Stays the same
D Decreases Increases Stays the same

The results of the experiments show that there are two ways to decrease the volume of an enclosed gas. Identify each way, then explain changes in particle behavior that are responsible for the volume decrease in each method
