Question

the actual amount of water vapor in an air and water mixture is known as?
○ dew point
○ relative humidity
○ absolute humidity

Explanation:

To solve this, we analyze each option:

• Dew point: Temperature at which air becomes saturated, not the amount of water vapor.
• Relative humidity: Ratio of actual water vapor to maximum possible, not the actual amount.
• Absolute humidity: Defined as the actual amount of water vapor in an air - water mixture.

Answer:

C. absolute humidity (assuming the options are labeled as A. dew point, B. relative humidity, C. absolute humidity; if the original option labels are different, adjust accordingly. Based on the given text, the correct option is the one with "absolute humidity".)
