Question 1 of 27070

In terms of humidity, when air is at its dew point, which of the following is true?

🔍 Key Concepts

• Dew point as the temperature where air becomes saturated • Difference between absolute humidity (actual water vapor content) and relative humidity (percentage of saturation) • What happens to relative humidity when air is cooled at constant moisture content

💭 Think About

• If you cool a parcel of air without adding or removing water vapor, what happens to its relative humidity as temperature drops toward the dew point? • At the dew point, is the air just starting to hold water vapor, or is it holding as much as it can at that temperature? • Which of the options talk about “highest” vs “lowest,” and which type of humidity is directly tied to the air reaching saturation?

✅ Before You Answer

• Be clear on the definition of dew point: temperature at which air becomes saturated (100% relative humidity) • Remember that absolute humidity is the actual mass of water vapor in a given volume, not a percentage • Check which choice correctly describes the condition of air when it is saturated at that temperature
