What to Focus On

  • Humidity means the amount of water vapour in air at a particular time and place.
  • Humidity is measured in percentage.
  • Humidity can be very low in cold dry air and as high as 5% in hot equatorial regions.
  • Relative humidity compares actual water vapour with maximum holding capacity at that temperature.
  • Relative humidity is expressed in percentage.
  • 100% relative humidity means saturation.
  • Condensation changes water vapour into liquid water or solid ice.
  • Condensation occurs when air cools below its dew point.
  • Dew point is the temperature at which air becomes fully saturated.

Common Mistakes to Avoid

Absolute humidity changes when temperature changes.

100% relative humidity means rain is already falling.

Fog and mist are the same because both reduce visibility.
