Solution

The correct option is D $3, 4$
The statements 3 and 4 are incorrect about the real gases.
1. The molecules of real gas attract each other. The molecules of ideal gas do not attract each other as there are no forces of attraction or repulsion between ideal gas molecules.
2. They show deviation from Boyle's and Charles' law. The real gases obey the van der Waals equation but they do not obey ideal gas equation.
3. Volume of gas molecules are not negligible. The volume of real gas molecules cannot be neglected in comparison to the volume of the container.
4. The molecules have some mass.

Q. Statement I: Under the conditions of low pressure and high temperature, the ideal gas laws are inaccurate.
Statement II: The deviation from the ideal gas law is due to non-negligible volume of the molecules and the interactions between molecules.

Choose the correct alternative:
The gas law which relates the volume of a gas to the number of molecules of the gas is:
(a) Avogadro's Law
(b) Gay-Lussac's Law
(c) Boyle's Law
(d) Charles' Law

Q. The main reason for deviation of gases from ideal behaviour is few assumptions of kinetic theory. These are
(i) there is no force of attraction between the molecules of a gas
(ii) volume of the molecules of a gas is negligibly small in comparison to the volume of the gas
(iii) Particles of a gas are always in constant random motion.

Q. Real gases show deviations from ideal gas law because molecules interact with each other. At high pressures molecules of gases are very close to each other. At very low temperatures intermolecular forces become significant. The deviation from ideal gas behaviour can be measured in terms of compressibility factor
