Answer:
(a) The dotted plot shows that is a
constant quantity, independent of pressure P. This signifies the ideal gas
behaviour.
(b)
The curve at temperature
is
closer to the dotted plot than the curve at temperature
. As the
behaviour of a real gas approaches the behaviour of a perfect gas when
temperature is increased, therefore,
.
(c)
Where the two curves meet, the value Of PV/T on Y-axis is equal to
R
As mass of oxygen gas =
(d)
If we obtained similar plots for
kg
of hydrogen, we will not get the same value of PV/T at the point, where the
curves meet on the Y-axis. This is because molecular mass of hydrogen is
different from that of oxygen.
For
the same value of
,
mass of hydrogen required is obtained from
gram
gram.
