Which of the following statements is not a correct assumption of the classicalmodel of an ideal gas? a. the molecules are in random motion. b. the volume of the molecules is negligible compared with the volume occupied bythe gas. c. the molecules obey newton's laws of motion. d. the collisions between molecules are inelastic. e. the only appreciable forces on the molecules are those that occur duringcollisions. a sample of an ideal gas is in a tank of constant volume. the sample absorbsheat energy so that its temperature changes from 300 k to 600 k. if v1 is theaverage speed of the gas molecules before the absorption of heat and v2 is theiraverage speed after the absorption of heat, what is the ratio v2/ v1? a. 1/2 b. 1 c. 2 d. 2 e. 4
