Volume occupied by the gas

Cohesive forces between gas molecules (correct)

Pressure exerted by the gas

Temperature of the gas

In the van der Waal's equation, what does the constant 'b' represent?

Temperature of the gas

Pressure exerted by the gas

Volume occupied by the gas (correct)

Cohesive forces

Why is the pressure of a real gas lower than that of an ideal gas?

Due to increased temperature

Due to cohesive forces between gas molecules (correct)

Due to higher number of moles present
