Figure Show plot of PV//T versus P for 1...

Figure Show plot of `PV//T` versus P for `1.00xx10^(-3)` kg of oxygen gas at two different temperatures.

(a) What does the dotted plot signify?
(b) Which is true: `T_(1) gt T_(2)` or `T_(1) lt T_(2)`?
(c) What is the value of `PV//T` where the curves meet on the y-axis?
(d) If we obtained similar plots for `1.00xx10^(-3)` kg of hydrogen, would we get the same value of `PV//T` at the point where the curves meet on the y-axis? If not, what mass of hydrogen yields the same value of `PV//T` (for low pressure high temperature region of the plot) ? (Molecular mass of `H_(2) = 2.02 u, of O_(2) = 32.0 u, R= 8.31Jmol^(-1)K^(-1).)

(a) The dotted plot corresponds to .ideal gas behaviour, (b) `T_(1) gt T_(2)`: (c) `0.26 J K^(-1)`, (d) No, `6.3 xx 10^(-5)` kg of `H_(2)` would yield the same value
