Question

According to the kinetic molecular theory, which statement describes an ideal gas?
(1) The gas particles are diatomic
(2) Energy is created when the gas particles collide
(3) There are no attractive forces between the gas particles
(4) The distance between the gas particles is small, compared to their size.

Answer 1

The correct answer is option 3. There are no attractive forces between the gas particles in an ideal gas. For an ideal gas to be achieved, the molecules are far from each other as possible where no attraction or collisions happen with each molecule.
