cuanchi · Answer

a)the temperature at which condensation occurs A technical definition follows: The dew point is the temperature at which the water vapor in a sample of air at constant barometric pressure condenses into liquid water at the same rate at which it evaporates.[4] At temperatures below the dew point, water will leave the air. The condensed water is called dew when it forms on a solid surface. The condensed water is called either fog or a cloud, depending on its altitude, when it forms in the air. https://en.wikipedia.org/wiki/Dew_point c)the point at which fog occurs Fog forms when the difference between air temperature and dew point is generally less than 2.5 °C or 4 °F https://en.wikipedia.org/wiki/Fog#Formation
