The perfect gas law relates the pressure p, absolute temperature T, mass m, and volume V of a gas. It states that
PV = mRT
The constant R is the gas constant. The value of R for air is 286.7 (N · m)/(kg · K). Suppose air is contained in a chamber at room temperature (20°C = 293 K). Create a plot having three curves of the gas pressure in N/m2 versus the container volume V in m3 for 20 ≤ V ≤ 100. The three curves correspond to the following masses of air in the container: m = 1 kg, m = 3 kg, and m = 7 kg.
