Problem
A student measures the pressure of carbon dioxide in a rigid container at 273K and finds it to be lower than the value predicted by PV=nRT. Which of the following adjustments would most effectively reduce the percent difference between the measured and predicted pressures while keeping the amount of gas and the container volume constant?
(a) Add additional carbon dioxide to the container.
(b) Compress the gas to a higher pressure by decreasing the container volume.
(c) Raise the temperature of the gas.
(d) Lower the temperature of the gas.
