Which statement describes the particles of an ideal gas based on the kinetic molecular theory?
(1) the gas particles are relatively far apart and have negligible volume.
(2) the gas particles are in constant, nonlinear motion.
(3) the gas particles have attractive forces between them.
(4) the gas particles have collisions without transferring energy.

(1) The gas particles are relatively far apart and have negligible volume

Explanation:

The Kinetic Molecular Theory was formulated to explain the behaviour of ideal gases. The main postulates of the theory are:

-The volume occupied by the gases is negligible when compared to the distance between them

- They do not experience any intermolecular forces of attraction or repulsion

-The collision between gas particles is completely elastic

-The gas particles are in constant random motion

Therefore the first statement which suggests that the gas particles are relatively far apart and have negligible volume is in accordance with the theory
