Q 1909512418.     Figure shows plot of PV/T versus P for
`1.00 xx 10^(-3)` kg of oxygen gas at two different
temperatures.

(a) What does the dotted plot signify ?
(b) Which is true : `T_1 > T_.2` or `T_1 < 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 `1.00 xx
10^(-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 = 8.31 J mol^(-1) K^(-1)`
