On a cold day, you take a breath, inhaling 0.4 L of air whose initial temperature is -10 degree C. In your lungs, its temperature is raised to 37 degree C. Assume that the pressure is 106 kPa and that the air may be treated as an ideal gas. What is the total change in translational kinetic energy of the air you inhaled number? Round your answer to the nearest whole.
