Which amongst the following is NOT one of the factors favouring evaporation?

1. Humidity
2. Supply of heat
3. Winds
4. Precipitation

The ratio between the absolute humidity of a given mass of air and the maximum amount of water vapour that it can hold at the same temperature:

1. Humidity
2. Dew Point
3. Relative humidity
4. Latent heat

Assertion (A): Under conditions of high relative humidity, the rate of evaporation of sweat from the skin decreases and the human being feels warm and uncomfortable.

Reason (R): The human body dissipates heat through perspiration and its evaporation.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R does not explain A.
3. A is true but R is false.
4. A is false but R is true.

The measure of the actual amount of water vapour in the air, regardless of temperature:

1. Absolute Humidity
2. Humidity
3. Dew Point
4. Relative Humidity
