1) Students are studying the behavior of a gas in a closed system. They conducted this experiment. 1. Remove the end cap from the tip of a 35-mL plastic syringe. 2. Remove plunger from the syringe and insert a small marshmallow into the syringe. 3. Place plunger back in syringe so the volume reading is approximately at the 15-mL mark. 4. Place a syringe tip cap over the tip of the syringe. 5. Pull the plunger out. What is the BEST description of what will happen when the plunger is pulled out? ) The marshmallow will expand because the volume A) inside the syringe has increased. As the pressure increased in the syringe the volume B) of the syringe and the marshmallow increased. The marshmallow expands because the volume has increased and the pressure inside the syringe has C) decreased. There is a direct relationship between volume and D) pressure so as the volume increases the pressure increases. The marshmallow shrinks.
