then using the combined gas law we calculate the final pressure of
the air.Here the intake gas pressure is the atmospheric pressure of
that day.

1)Normal lung capacity is about 0.32L. On a cool fall day, the outside air has a temperature of 13°C while the temperature inside the lung at 37°C. The pressure outside the lung is 749 torr, and the pressure inside the lung is 733 torr. How many mL of air must be inhaled to fill the lungs? 2) Calculate the pressure inside a 375mL container filled with 37.2g of He at a temperature of -35°C. 3) Calculate the molar volume of...

Q1 Otto Cycle Bookwork Question An air standard Otto cycle:- 1. Draws air from the environment at 100 kPa and 5°C. 2. The cycle has a compression ratio of 9.2: 1. 3. Heat (880 kJ/kg) is added to the compressed gases at constant volume. 4. The working fluid is air, a perfect gas with ratio of specific heats y = 1.4 and gas constant R = 287 J/kgk. Follow the instructions below: a) Describe each of the four processes from...
