The next three questions all go together. 21. Expired air is saturated with water vapor and generally contains more of it than does inspired air. There is usually a net loss of water from the body due to breathing. Water vapor pressure in the at saturation in the lungs (at 37°C) is 47 mmHg, while in expired air at 33°C it is 37.7 mmHg. Consider the case of someone who is breathing dry air in and moist air out at...

At 22.0 degrees Celsius an "empty" 30-ml syringe had a volume of 5.0 ml. After a liquid is introduced and the temperature is raised to 32.0 degrees Celsius, the volume becomes 10.2 ml. The barometer pressure is 745.8 mmHg, 1. what was the pressure of the air inside the syringe when the syringe was "empty"? 2. What is the pressure of the air inside the syringe after the liquid has been introduced and the temperature raised to 32.0 degrees Celsius?...

Find P air and V air ..
Water vapor accounts for part of the gas volume and S8 lle volum u sued must be corrected for the water vapor present. The vapor pressure of the water depends on temperature and the vapor pressure of water (PH,o) at different temperatures can be found in Table 1. If a Ph,o value at a particular temperature is not usted in the table, then it has to be found through the interpolation method from...
