According to kinetic molecular model, in gases

Question 1 Report

The particles are closely packed together, they occupy minimum space and are usually arranged in a regular pattern

The particles occur in clusters with molecules slightly farther apart

The molecule are very fast apart and occupy all the space made available

The particle vibrate about fixed positions and are held together by the strong intermolecular bonds between them

Answer Details

According to the kinetic molecular model, in gases, the molecules are very fast apart and occupy all the space made available. This means that gas molecules are in constant random motion and they move freely in all directions without any regular arrangement. They collide with each other and with the walls of the container, exerting pressure. The temperature of the gas is related to the average kinetic energy of the gas molecules. The higher the temperature, the faster the gas molecules move, and the higher the kinetic energy.
