Question

I really need help with this question. ;-;

What is the relationship between temperature, dew point temperature, and air pressure?

Answer 1

The dew point is the temperature the air would be at if it saturated at the present level of water vapour content - in other words if we cooled air, the point at which is was saturated with water vapour is it's dew point. So dew point is related to air volume which is related to both temperature and pressure.

Not accurate figures but if air was at a certain temperature and contained say 80% relative humidity and the air cooled, then eventually (with the same amount of water vapour content) it would reach 100% rH and saturate. That would be the dew point temperature

Thank you so much! ^-^
