Question

Real gases approaches ideal gas at high temperature and low pressure because

$A$. Inter atomic separation is large

$B$. Size of the molecule is negligible when compared to inter atomic separation

• A. a & b are true
• B. only a is true
• C. only b is true
• D. a & b are false

Answer 1

The correct option is A a & b are true

Generally, a gas behaves more like an ideal gas at higher temperature and lower pressure as the forces against intermolecular forces becomes less significant compared to the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.
