Document Summary
The average energy of particles in a fluid are governed by the temperature. The > temperature (c) the > the energy. Some particles may have energy > than the average: these can escape from the attractive forces holding the liquid together (evaporation) The warmer the temp, the greater the water vapour pressure (more water evaporated into atmosphere) Energy is affected by temp, as you increase temp, energy increases. Temperature (c) drops- capacity of air to hold water vapour drops- ph2o drops. Greater changes happen from a chemical perspective. Changes in ventilation as you go up in altitude. Partial pressure drops as we go up in altitude. Pco2: dictated by co2 production from krebs and/or buffering, co2 production stays the same, as you go up in altitude, see drop in partial pressure of co2 in the blood o. Pco2 drops because co2 production stays the same. 115mmhg- ventilation starts to increase ph- becoming more basic as co2 is removed.
