HUMIDITY: Water vapour present in the air. MOISTURE: Water vapour present in the air, or water traces present in a solid substance, like food item, cotton, soil etc. The term HUMIDITY is preferred for air or used in the context of weather and climate. For example, we say that, today humidity in air is more instead of saying today air has more moisture.
Absolute humidity is the mass of water vapor divided by the mass of dry air in a volume of air at a given temperature. The hotter the air is, the more water it can contain. Â­Relative humidity is the ratio of the current absolute humidity to the highest possible absolute humidity (which depends on the current air temperature). A reading of 100 percent relative humidity means that the air is totally saturated with water vapor and cannot hold any more, creatinÂ­g the possibility of rain. This doesn't mean that the relative humidity must be 100 percent in order for it to rain -- it must be 100 percent where the clouds are forming, but the relative humidity near the ground could be much less.
