ASSERTION- Humidity decreases the rate of evaporation. REASON- In humid air the intermolecular space is occupied by water molecules. *
Answers
Answer:
both are true
Explanation:
evaporation is a process by which extra water vapour is added to atmosphere so naturally with more humidity evaporation rate is decreased
Answer:
True
Explanation:
humidity, moisture content of the atmosphere, a primary element of climate. Humidity measurements include absolute humidity, the mass of water vapor per unit volume of natural air; relative humidity (usually meant when the term humidity alone is used), the ratio of the actual water-vapor content of the air to its total capacity at the given temperature; Humidity is measured using a hygrometer. The rate of evaporation decreases as the moisture content of the air increases and approaches saturation.
An increase in the amount of humidity in the air increases the speed only by a small amount. Since humidity can vary so much, and since the amount of change of speed with an extreme change in humidity is less the 0.5%, the speed of sound in air is usually simply measured in dry air, neglecting the effect of humidity.
The amount of water vapor in the air influences density. Water vapor is a relatively light gas compared to diatomic Oxygen and diatomic Nitrogen - the dominant components in the air.
When water vapor content increases in the moist air the amount of Oxygen and Nitrogen decreases per unit volume and the density decreases because the mass is decreasing.
