प्रश्न
On what does the percentage of relative humidity depend?
उत्तर
Relative humidity is determined by the amount of water vapour in the atmosphere (called absolute humidity) in proportion to the vapour holding capacity at the same temperature and same volume.
Relative humidity (%) `=("Absolute"-"Humidity"(%))/("Vapour holding capacity")xx100 `
Relative humidity is inversely proportional to the temperature. When the temperature decreases, Relative humidity increases. It is low when the temperature is high.
Therefore, Relative humidity is usually higher in mornings and nights but lower in afternoons due to the increase in temperature.
