The Van der waals equation is an equation of state for a fluid composed of particles that have a non-zero volume and a pair wise attractive inter-particle force ( Van der waals force) The equation is :

\( (p+\dfrac{n^2a}{V^2})(V-nb)=nRT\)

**Physical significance of ‘a’: **

‘a’ is a measure of the magnitude of intermolecular attractive forces within a gas.

**Physical significance of ‘b’:**

‘b’ is a measure of the volume of a gas molecule. V is the total volume of the container containing the fluid.

Critical temperature for carbon dioxide and methane are 31.1°C and – 81.9°C respectively. Which of these has stronger intermolecular forces and why?

In terms of Charles’ law explain why -273°C is the lowest possible temperature.

What would be the SI units for the quantity \(\dfrac{pV^2 T^2}{n}\)

A mixture of dihydrogen and dioxygen at one bar pressure contains 20% by weight of dihydrogen. Calculate the partial pressure of dihydrogen.

2.9 g of a gas at 95°C occupied the same volume as 0.184 g of dihydrogen at 17°C, at the same pressure. What is the molar mass of the gas?.
