An Inquiry Based Activity PROPERTIES OF GASES An Inquiry Based Activity

Station 1: Paper Towel What happened to the towel? WHY? What property does this illustrate?

Station 2: Balloon on a Balance Which property does this illustrate?

Station 3: Marshmallow in Syringe Which envriomental condition are you controlling? LEFT PHOTO: note the size of the marshmallow (3 cc) RIGHT PHOTO: note the size of the marshmallow (about 2.3 cc) What is the explanation for this?

Station 4: Heating and Cooling a Gas Which environmental condition are you controlling here? How can you explain what you are seeing? What is the relationship between temperature and volume?

Station 5: Pumping Air What type of matter is being moved here? What is the relationship between the number of particles and pressure?

Station 6: Water Rising How can you explain what is happening here? Consider: molecules in the flask when the candle is lit and the molecules when the candle is extinguished…

Station 7: Crushing Can What does this demonstration illustrate? Consider the following: Pressure inside can? Pressure outside can? Temperature in can? Temperature change and it’s Impact on the molecules?

Summary Questions: Base your answers on the phenomena we observed in the lab What is the relationship between pressure and volume? What is the relationship between temperature and volume? If the number of particles are increased, what happens to the volume? If the number of particles are decreased, what happens to the volume? If the number of particles are increased, what happens to the pressure? If the number of particles are decreased, what happens to the pressure? What is the relationship between pressure and temperature? In a closed system, if temperature is increased, what happens to the number of particles?
