3. The air (treat it as N2, diatomic, ideal) in a bicycle tire has a volume of 2.5 liters. The temperature and pressure of the gas are 300 K and 3.20 × 10° Pa, respectively. A cyclist then brings the gas pressure up to 6.68 × 105 Pa without changing the temperature or volume of the gas. (a) How many moles of air must be pumped into the tire? (b) What is the change in total internal energy?
