Question

The behaviour of the gases, which can be easily liquified, is like that of the

• A. triatomic gases
• B. ideal gases
• C. van der Waals gases
• D. all of the above

Answer 1

The correct option is C van der Waals gases

Van der Walls equation takes into account inter atomic forces between gas particles which is not considered in the ideal gas model. Since simplicity of liquification of a gas depends upon forces between its particles, Van der Walls equation is followed by easily liquifieable gases.

$(P+a(\frac{n^2}{V^2}\left)\right)(V-nb)=nRT$

Parameter a takes into account interatomic forces.
