Final answer:
The dew point is the temperature at which air reaches 100% relative humidity and water vapor condenses into liquid water. To find the dew point, we can use the relative humidity and the temperature. For example, if the temperature is 20.0°C and the relative humidity is 39.0%, we can find the dew point using these values.
Step-by-step explanation:
The dew point is the temperature at which air reaches 100% relative humidity. It is the point at which water vapor in the air begins to condense into liquid water. For example, if the temperature is 20.0°C and the relative humidity is 39.0%, we can find the dew point by multiplying the relative humidity by the saturation vapor density and converting it to a temperature.
