46Humidity and Relative Humidity Humidity is the amount of water vapor in the airRelative humidity is a measure of the amount of water vapor that the air is holding, compared to the amount it can hold at a specific temperature
47Humidity and Relative Humidity When the air is holding as much moisture as it can, it’s said to be saturated
49In the cool of the morning, the air can’t hold as much moisture In the cool of the morning, the air can’t hold as much moisture. We often have dew on a summer morningOnce the air has warmed, the relative humidity drops since the air can hold more moisture
50You’ve seen water on the outside of a cold drink? The cold air around the glass causes a lower temperature at which the air is saturated
