Question

The scale for humidity has a minimum value of 40%. However, if you could change the humidity to zero and set a 70°F difference between temperatures, would precipitation occur? Why or why not? What type of weather would you expect?

Answer 1

Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. It requires less water vapor to attain high relative humidity at low temperatures; more water vapor is required to attain high relative humidity in warm or hot air.
