Understanding the Ideal Gas Law

What assumption is made about gas particles' volume in the ideal gas law?

• Particles have significant volume

• Volume of particles increases with pressure

• Volume of particles decreases with temperature

• Particles have no volume

How do gas particles behave according to the ideal gas law assumptions?
