Document Summary

Relationship b/w temp and water vapour pressure. The higher the temp, the more water is evaporated into atmosphere so more water vapour pressure. As temp decreases, the cooler it gets and less water vapour pressure. Inside our lungs, will be at 37 degrees celsius at alveolar level. Once you"re outside, breathe in -10 air, theres no water vapour in air you"re inspiring because water vapour is unable to become evaporated into atmosphere. Energy is effected by temperature in a particular environment. Air will be warmed so will have water molecules evaporating or leaving the blood stream. Greater the temp, more energy, and more water molecules leaving blood stream. When you exhale, that transition from vapour to liquid (condensation) and when it condenses you can see your breath. Can lose a lot of moisture from the blood plasma and become dehydrated from perspiration and every time you exhale, a lot of moisture leaving the blood plasma.
