Answer 1

Answer:

hope this is helpfull

chapter- states of matter

Answer 2

Answer:

• The term 'a' in the vander Waals equation refers to the magnitude of the attractive forces that exist between gas molecules.
• The larger the intermolecular forces, the higher the value of a will be.
• As a result, 'a' denotes the magnitude of attraction and repulsion forces between gas molecules.

Explanation:

The van der waals equation

[P + a(n/V)2] (V/n - b) = RT

• The constants a and b are called van der Waals constants.
• They have positive values and are characteristic of the individual gas.
• If a gas behaves ideally, both a and b are zero, and van der Waals equations approaches the ideal gas law PV=nRT.
