- I put air in the tires of my car during the summer, while it was 28.8 °C outside (about 83.8 °F). My tires say to fill them to a pressure of 203,000 Pa. Boltzmann's constant is 1.38 * 10 ^ - 23 * J / K A) If my tires have a volume of 0.0100 m³, how many air molecules are in the tire? N = molecules B) These tires go all summer without losing any air, however come fall the temperature drops down to 8.65 °C (about 47.6 °F). Assuming the volume doesn't change (because it doesn't) what is the new pressure in my tires? P=An airplane is pressurized with air to 650 mmHg. a. If air is 21% oxygen, what is the partial pressure of oxygen on the plane? b. If the partial pressure of oxygen drops below 100 mmHg, passengers become drowsy. If this happens, oxygen masks are released. What is the total cabin pressure at which oxygen masks are dropped?A car tire has an inner radius of 45.46 cm has a low pressure of 195 kPa. The tire is recommended to be inflated to 248 kPa. At the low pressure the tire outer radius is 56.65 cm and fully inflated is 67.81 cm. The outside temperature is 17 0C. What is the mass of the air to inflate the tire? How many air molecules are added to properly inflate the tire?
