To conduct some experiments, a 10.0-L flask equipped with a movable plunger, as illustrated here, is filled with enough H2 gas to come to a pressure of 20 atm.
a. In the first experiment, we decrease the temperature in the flask by 10oC and then increase the volume. Predict how the pressure in the flask changes during each of these events and, if possible, how the final pressure compares to your starting pressure.
b. Once again we start with the pressure in the flask at 20 atm. The flask is then heated 10oC, followed by a volume decrease. Predict how the pressure in the flask changes during each of these events and, if possible, how the final pressure compares to your starting pressure.
