Which of the following cities has both the highest water vapor content AND lowest relative humidity?

City A: Temperature = 90 °F, Dew Point Temperature = 75 °F

City B: Temperature = 70 °F, Dew Point Temperature = 65 °F

City C: Temperature = 20 °F, Dew Point Temperature = 10 °F

Answer #1

the dew point temperature is the temperature above which the water vapour will convert into liquid water.

and the relative humidity is the ratio os the current water vapor content to the maximum amount of water that can be present in the air

therefore although the temperature may be high yet the relative humidity can be considerably low

hence the correct option must be CITY A

    1. (relative humidity) The partial pressure of water vapor in air is usually less than the equilibrium vapor pressure (or saturation pressure) at the ambient temperature; this is why a cup of water will spontaneously evaporate. The ratio of the partial pressure of water vapor to the equilibrium vapor pressure (at the same temperature) is called the relative humidity. Saturated air, at 100% relative humidity, would be in equilibrium with a cup of liquid water. The saturation pressure depends strongly...

    We are learning about relative humidity. 1st part- what is the water vapor content at 25 degree C air if its relative humidity is 50%? 50=10/20 x 100% gives me the water vapor content of 10g/kg. 2nd part- If the air was at 25 degree C at sea level, and rises to 1,000 meters, then what will its temperature be? It will drop by 10 degree C, so the temperature will be 15 degrees C. At 15 degree's C the...

  • Humidity is the amount of water vapor in the air at a given time

    Humidity is the amount of water vapor in the air at a given time. At warm temperatures, air can hold more moisture than it can at cold temperatures. Relative humidity is the amount of vapor the air is holding expressed as a percentage of the amount the air is capable of holding. For example, at 86 degrees Fahrenheit, air can hold a maximum of 30.4 grams of water per cubic meter. If the air at the same temperature is holding...
