\(2\,gm \) of \({O_2}\) at \({27\,^o}C\) and \(760\,mm\) of \(Hg\) pressure has volume ............. \(\mathrm{lit.}\)
1 \(1.5\)
2 \(2.8\)
3 \(11.2\)
4 \(22.4\)
Explanation:
\(P V=n R T\) \(\Rightarrow V=\frac{n R T}{P}\) \(=\frac{\frac{2}{32} \times 0.0821 \times(27+273)}{\frac{760}{760}} \,L\) \(=1.53\, L\)

Pressure of a gas in a vessel can be measured by
1 Barometer
2 Manometer
3 Stalgometer
4 All the baove
Explanation:
(b) Barometer is used to measure atmospheric pressure of mixture of gases. Staglometer is used to measure surface tension. Only manometer is used to measure pressure of pure gas in a vessel.

Volume occupied by a gas at one atmospheric pressure and \({0\,^o}C\) is \(V\, mL\). Its volume at \(273\, K\) will be
1 \(V \,ml\)
2 \(V/2\, ml\)
3 \(2 \,V\)
4 None of these
Explanation:
(a) \({0\,^o}C\) is equivalent to \({273\,^o}K\) \(i.e.\) conditions are same so volume will be \(V\, ml\).

Which one of the following statements is wrong for gases
1 Gases do not have a definite shape and volume
2 Volume of the gas is equal to the volume of the container confining the gas
3 Confined gas exerts uniform pressure on the walls of its container in all directions
4 Mass of the gas cannot be determined by weighing a container in which it is enclosed
Explanation:
(d) The mass of gas can be determined by weighing the container, filled with gas and again weighing this container after removing the gas. The difference between the two weights gives the mass of the gas.
