Questions and Answers

What does the van der Waal's equation account for in real gases?

  • 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
  • Due to decreased volume
