Temperature is a scalar quantity with magnitude, but no direction.
Temperature is really a measure of the average kinetic energy of a gas. Assume the average velocity of oxygen at room temperature is 480 meters per second. Using the kinetic energy formula along with your answer from question 8, calculate the kinetic energy for oxygen. Assume the average velocity of nitrogen at room temperature is 510 meters per second. Using the kinetic energy formula along with your answer from question 8, calculate the kinetic energy for nitrogen.
