In a laboratory activity, the volume of helium gas in a rigid cylinder with a movable piston is varied by changing the temperature of the gas. The activity is done
at a constant pressure of 100 kPa. Data from the activity are plotted on the graph
below. Determine the volume of the He(g) at a temperature of 300°K.
