The kinetic theory of matter is a model used to describe the behaviour of particles (atoms or molecules) in an ideal gas. There are a number of assumptions made in the kinetic model for an ideal gas.
Which one of the following assumptions is not correct?
The forces between particles are negligible except during their collisions.
The volume occupied by the gas particles themselves is negligible compared to the total volume of the container.
The time duration of each collision is significantly longer than the time interval between collisions.
All collisions of particles with each other and the container walls are perfectly elastic.
