                                    How are pressure and volume related for a gas?

                              If we trap a constant amount of air in a cylinder at constant temperature
                           how will the pressure behave if the gas is compressed by shrinking the volu


                                                  Can you sketch and label a graph?
                                                    What is the dependent variable?
