Consider the procedures in a simple experiment used to demonstrate the behavior of gases. 1. Remove the end cap from the tip of a 35-mL plastic syringe. 2. Remove the plunger from the syringe and insert a balloon into the syringe. 3. Place the plunger back in the syringe so the volume reading is approximately at the 15-mL mark. 4. Using a finger, seal the syringe. 5. Pull the plunger out. Select ALL of the statements that help to explain what occurs once the plunger is pulled out.

• The pressure inside the balloon increases.

• The pressure inside the syringe chamber decreases.

• The lower pressure on the balloon causes its volume to increase.

• When the syringe plunger is pulled out, the amount of gas increases.

• When the syringe plunger is pulled out, the volume of the chamber increases.

What is the best conclusion for the events taking place on a molecular level in the images seen here?

• Kinetic energy decreases from left to right. The fourth state, plasma, has the most kinetic energy and the atoms disassociate.

• Heat energy is continuously added at each step. As energy is added, the molecular motion/kinetic energy increases, and matter changes state. In the last state, plasma, enough energy has been added to cause the atoms to disassociate into ions.

• At each step, the state of matter changes. At each step, the molecular motion of the atoms increases because there is a decrease in pressure. During the final step, there is so little pressure that the atoms separate into protons and electrons.

• Matter changes state when there is a change in temperature. In each step, the temperature decreases causing a change in state. At the last state, plasma, the temperature is so low that the atoms cannot stay together and they disassociate into ions.
