Relative Humidity is a ratio of?

Question

a.) warm air to dry air

b.) how much water air can hold at a given temperature.

c.)how much hear air can hold with a given moisture.

d.) moist air to dry air

e.)how much water capor is in the air compared to how

much the air can hold at that temperature.

Answer 1

It's the ratio of the actual vapor pressure of water to the saturation vapor pressure at that temperature.

The closest answer is "e," but that actually perpetuates a myth that air can "hold" so much water, like it's some sort of sponge.  Tell your teacher to look at this link http://www.atmos.umd.edu/~stevenb/vapor/...

or most modern atmospheric thermodynamics texts.

Answer 2

Relative humidity is the ratio of vapor pressure and saturation multiplied. That is to say, relative humidity is a measure of how water vapor is present in a column of air compared to how much moisture is needed to saturate air at a given temperature. With that being said, the answer should be e.

Answer 3

The answer is'e'.

Relative humidity is defined as the ratio of the amount of water vapour actually present in the air to the amount of water vapour required to saturate the air  at that temperature.

Answer 4

E.) It's how much water vapor is IN the air, over how much water vapor COULD be in the air.

Answer 5

b) Relative humidity is the amount of moisture in the air at a given temp. divided by the maximum amount of moisture it can hold at a given temp.
