The air temperature is 70 degrees, and the relative humidity is 90%. Which conclusion can be made? (1 point)

Question

The dew point temperature is 90% of the air temperature.

The air holds little water vapor and is relatively dry.

The amount of water vapor in the air is 90% of what the air can hold.

The temperature must rise in order for air to become saturated with water vapor

Answer 1

The correct conclusion is:

The amount of water vapor in the air is 90% of what the air can hold.

This is because relative humidity is defined as the amount of moisture in the air compared to the maximum amount the air can hold at a given temperature, expressed as a percentage. In this case, with a relative humidity of 90%, the air holds 90% of its capacity for water vapor at 70 degrees.
