Figure 12.8 shows plot of TPV versus P for 1.00×10–3 kg of oxygen gas at two different temperatures.
(a) What does the dotted plot signify?
(b) Which is true: T1>T2 or T1<T2 ?
(c) What is the value of TPV where the curves meet on the y-axis?
(d) If we obtained similar plots for 1.00×10–3 kg of hydrogen, would we get the same value of TPV at the point where the curves meet on the y-axis? If not, what mass of hydrogen yields the same value of TPV (for low pressure high temperature region of the plot) ? (Molecular mass of H2 = 2.02 u, of O2 = 32.0 u, R = 8.31 J mo1–1 K–1.)
