Show Hint
Atmospheric Terms. Humidity: Amount of water vapor in the air. Moisture: Presence of liquid water. Viscosity: Resistance to flow. Density: Mass/Volume.
- Humidity specifically refers to the concentration of water vapor present in the air It can be expressed as absolute humidity (mass of water vapor per unit volume or mass of dry air) or relative humidity (ratio of current water vapor pressure to saturation vapor pressure at a given temperature)
- Moisture is a more general term referring to the presence of a liquid, especially water, often diffused or condensed
- Viscosity is a measure of a fluid's resistance to flow
- Density is mass per unit volume
