Experiment 2: Barometric Pressure Questions 1. How does your barometer allow you to measure changes in atmospheric pressure? 2. In what direction did the arrow point for high pressure? For low pressure? Why? 3. How did the volume of the gas in the container change as the pressure outside increased and decreased? What does this tell you about the relationship between pressure and volume of a gas?

Physics 320 Experiment 1 continued Experiment 3: Marshmallow Madness Questions 1. How did you decrease the air pressure in the syringe? What happened to the marshmallow under these conditions? 2. What can you conclude from this experiment about the composition of marshmallows? 3. What would happen to a marshmallow if you put it on the moon (where there is very little atmosphere and thus very low pressure)? What would happen to a marshmallow on Jupiter (which has a very dense atmosphere)? Phys320 Lab Page 3 Experiment 1...
