A gas such as carbon monoxide would be most likely to obey the ideal gas law at
1 High temperature and high pressure
2 Low temperature and low pressure
3 High temperature and low pressure
4 Low temperature and high pressure
Explanation:
Real gases show ideal gas behaviour at high temperature and low pressure.

A gas deviates from ideal behaviour at a high pressure because its molecules
1 Have kinetic energy
2 Are bound by covalent bonds
3 Attract one another
4 Ahow the Tyndall effect
Explanation:
Some attractive forces exist between the molecules of real gases. When a molecule approaches the wall of the container it experiences an inward pull as a result of attractive force exerted by the neighbouring molecules inside the vessel. Therefore the observed pressure is less than the ideal pressure and hence gas deviates from ideal behaviour at high pressure.

If helium is allowed to expand in vacuum, it liberates heat because
1 helium is an inert gas
2 helium is an ideal gas
3 the inversion temperature of helium is very low
4 helium is one of the lightest gases
Explanation:
Helium shows heating effect atroom temperature as it possesses very low values of inversion temperature.

Which gas shows real behaviour?
1 \({\rm{1g}}\,{\rm{of}}\,{{\rm{H}}_{\rm{2}}}\) in \(\mathrm{0.5 \mathrm{~L}}\) flask exerting pressure \(\mathrm{24.63 \mathrm{~atm}}\) at \(\mathrm{300 \mathrm{~K}}\)
2 \({\rm{8g}}\,{\rm{of}}\,{{\rm{O}}_{\rm{2}}}\) at STP occupies 5.6 Litre
3 1 mole \(\mathrm{\mathrm{NH}_{3}}\) at \(\mathrm{300 \mathrm{~K}}\) and \(\mathrm{1 \mathrm{~atm}}\) occupies volume 22.4 Litre
4 5.6 Litre of \(\mathrm{\mathrm{CO}_{2}}\) at \(\mathrm{\mathrm{STP}}\) is equal to \(\mathrm{11 \mathrm{gm}}\)
Explanation:
For ideal gas, \(\mathrm{\mathrm{PV}=\mathrm{nRT}}\) For one mole of gas, the volume occupied must be \(\mathrm{22.4 \mathrm{~L}}\) at STP conditions.
