The air temperature is 70 degrees and the relative humidity is 90%. Which conclusion can Be made?

Question

The temperature must rise in order for air to become saturated with water vapor
The dew point temperature is 90% of the air temperature
The air holds little vapor and is relatively dry
The amount of water vapor in the air is 90% of what the air can hold

Answer 1

The correct conclusion from the given information is:

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

This means that the air is close to being saturated with water vapor at 70 degrees Fahrenheit and 90% relative humidity. In this case, the air is holding 90% of the maximum amount of water vapor it can hold at that temperature.
