Question

The amount of humidity in the atmosphere is a measure of ____ in the air .
•Heat
•Temperature
•Chemical
•Moisture​

Answer 1

Answer:

Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye.[1] Humidity indicates the likelihood for precipitation, dew, or fog to be present. The amount of water vapor needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air decreases it will eventually reach the saturation point without adding or losing water mass. The amount of water vapor contained within a parcel of air can vary significantly. For example, a parcel of air near saturation may contain 28 grams of water per cubic metre of air at 30 °C, but only 8 grams of water per cubic metre of air at 8 °C.

Three primary measurements of humidity are widely employed: absolute, relative and specific. Absolute humidity describes the water content of air and is expressed in either grams per cubic metre[2] or grams per kilogram.[3] Relative humidity, expressed as a percentage, indicates a present state of absolute humidity relative to a maximum humidity given the same temperature. Specific humidity is the ratio of water vapor mass to total moist air parcel mass.

Humidity plays an important role for surface life. For animal life dependent on perspiration (sweating) to regulate internal body temperature, high humidity impairs heat exchange efficiency by reducing the rate of moisture evaporation from skin surfaces. This effect can be calculated using a heat index table, also known as a humidex.

Answer 2

The amount of humidity in the atmosphere is a measure of moisture in the air.

Explanation:

• Moisture is the tiny drops of liquids especially water in air or ground or on any surface. It is defined as small amount of wetness.

• Humidity is the amount of water vapor in the air.

• If there is a lot of water vapor in the air, the humidity will be high.

• Higher the humidity, wetter it feels outside.

• In weather reports, humidity is usually explained as relative humidity. Relative humidity is the amount of water vapor actually in the air, expressed as a percentage of the maximum amount of water vapor the air can hold at same temperature.

• When humidity is high, the air is clogged with water vapor and there is no room for anything else.

• When we sweat in humid air, it becomes difficult to cool off as the sweat can't even evaporate into air like it needs to.
