Why can scientists ignore the forces of attraction between particles in a gas under ordinary conditions?
They are too weak to have an effect at the temperatures at which most gases exist.
They do not exist for particles that have kinetic energy.
They are too weak to have an effect at great distances between gas particles.
The correct answer is: They are too weak to have an effect at the temperatures at which most gases exist.
Under ordinary conditions, such as the typical temperatures and pressures found on Earth, the forces of attraction between particles in a gas are relatively weak compared to the kinetic energy of the particles. This means that the particles are constantly moving and colliding with each other, and the forces of attraction between them do not significantly affect their overall behavior. Therefore, when studying gases under ordinary conditions, scientists can usually ignore the forces of attraction between the particles.
