Movement of gas molecules is affected by temperature. Its average kinetic energy is directly related to the temperature of gases. What might happen to the kinetic energy of gas molecules as temperature decreases?
*
1 point
a. as the temperature decreases the average kinetic energy of gas molecules decreases
b. as the temperature decreases the average kinetic energy of gas molecules increases
c. as the temperature decreases the average kinetic energy of gas molecules remains the same
d. as the temperature decreases the average kinetic energy of gas molecules fluctuates.
