Which of the following statements are true?Check all that apply.a. There are gas molecules that move faster than the average.b. The average speed of gas molecules increases with temperaturec. All the gas molecules in a sample have the same Kinetic energyd. There are gas molecules that move slower than the average.e. The average Kinetic energy of gas molecules increases with temperature.

Options a) and d) are correct because that's what an average speed means. Gas molecules have different speeds, and what we can easily measure is the average speed of all of them, this would logically mean that there are some molecules that move at a higher/lower speed than the average.

Option e) is correct because the average kinetic energy K is dependant on the temperature T as seen by the formula K=1.5*R*T. This would also mean that option b) is correct because a higher kinetic energy means there is a higher speed.
