QUESTION 14 Consider the following statements. Which is true about an ideal gas? CP Gas partides are not attracted to each other Gas particles behave independently of each other. Gas particles collide with each other and with the walls of the container without losing any energy. The volume occupied by the gas particles is very small compared to the total volume of the container which holds the gas. All of the above we true for gases.
