Is this true there are no forces of attraction between the particles in a gas?

It's not entirely true that there are no forces of attraction between particles in a gas. While gas particles are far apart and move freely, there are weak intermolecular forces present, such as van der Waals forces. However, these forces are negligible compared to the kinetic energy of the particles at typical gas temperatures, allowing them to behave independently. Therefore, while attraction exists, it does not significantly affect their behavior under normal conditions.
