Ideal Gas
CHXI06:STATES OF MATTER

314184 When the pressure of 2 litres of \(\mathrm{\mathrm{O}_{2}}\) gas is doubled and its temperature is also doubled from \(\mathrm{300 \mathrm{~K}}\) to \(\mathrm{600 \mathrm{~K}}\), the final volume of the gas is

1 4 lit
2 20 lit
3 40 lit
4 2 lit
CHXI06:STATES OF MATTER

314185 When an ideal gas undergoes unrestrained expansion, no cooling occurs because the molecules

1 are above the inversion temperature
2 exert no attractive force on each other
3 do work equal to loss in kinetic energy
4 collide without loss of energy

314186 \(\mathrm{22 \mathrm{~g}}\) of solid \(\mathrm{\mathrm{CO}_{2}}\) is enclosed in a bottle of one litre properly closed. If temperature of bottle is raised to \(\mathrm{25^{\circ} \mathrm{C}}\) to sublime all the \(\mathrm{\mathrm{CO}_{2}}\), the pressure in bottle is

314188 A gas is heated in such a way so that its pressure and volume both become double. Again by lowering temperature, one fourth of initial number of moles of air has been taken in, to maintain the double volume and pressure. By what fraction, the temperature must have been raised finally?

1 \(\mathrm{1 / 5}\)
2 \(\mathrm{4 / 5}\)
