Question

which statement accurately describes humidity?
humidity is a measure of dew in the air
colder air promotes more evaporation.
cold air holds more moisture than warm air.
humidity refers to the amount of water vapor in the air.

Explanation:

• Humidity is about water vapor in air, not dew. Dew is liquid water formed when air cools.
• Warmer air promotes more evaporation as it has more energy to convert liquid water to vapor. Colder air does not.
• Warm air holds more moisture than cold air. As air warms, its capacity to hold water vapor increases.
• By definition, humidity refers to the amount of water vapor in the air.

Answer:

Humidity refers to the amount of water vapor in the air.
