2PRACTICE PROBLEM
Constant pressure of a gas sample can be attained by fitting a container with a movable piston. A gas in such a container is maintained at a constant pressure of 800 Pa. If the gas is oxygen (molar mass 32.00 g/mol) and its temperature varies between 40°C and -70°C, calculate the range of root-mean-square speeds for oxygen molecules.
