how is the velocity of gas molecules impacted by temperature? the velocity of each molecule increases as…

Brief Explanations:

According to the kinetic - molecular theory of gases, temperature is a measure of the average kinetic energy of gas molecules. As temperature increases, the average kinetic energy of gas molecules increases. Since kinetic energy is related to velocity ($KE=\frac{1}{2}mv^{2}$), an increase in average kinetic energy leads to an increase in the average molecular velocity. It's important to note that we refer to the average velocity, not the velocity of each individual molecule as individual molecules have a distribution of velocities.

Answer:

C. The average molecular velocity increases as temperature increases.
