Question

10 mark for review the diagrams above use arrows to represent the speed of a gas particle. which of the diagrams best represents the speed of the particles of a gas at a fixed temperature, and why? a diagram 1, because all the particles have the same speed. b diagram 1, because the particles are moving in different directions. c diagram 2, because the particles have a net kinetic energy of zero. d diagram 2, because the particles have a variety of different speeds.

Explanation:

At a fixed temperature, gas particles have a distribution of speeds due to the Maxwell - Boltzmann distribution. They do not all have the same speed. Diagram 2 shows particles with a variety of different speeds which is consistent with the behavior of gas particles at a fixed temperature.

Answer:

D. Diagram 2, because the particles have a variety of different speeds
