Water vapor in the air.
What types of climate are more humid?
Rainforest, monsoon, tropical, oceanic, etc.
How do we know that the humidity is high or low?
If it's high, the water on the wet bulb evaporates slowly, and the wet-bulb temperature doesn't change much.
If it's low, the water on the wet bulb evaporates rapidly, and the wet-bulb temperature drops by large amount.
True or False?
Warm air can hold less water vapor than cool air.
False.
Warm air can hold more water vaor than cool air.
We can measure relative humidity with a ___________.
Psychrometer
What is humidity?
The amount of water vapor in the air.
How does a psychrometer work?
It has two thermometers, a wet-bulb thermometer (covered with a moist cloth) and a dry-bulb thermometer. When the psychrometer is slung or spun, air blows over both thermometers.
What depends on the air to hold vapor?
The temperature :D
What is humidity?
The percentage of water vapor that is actually in the air compared to the to the maximum amount of water vapor that the air can hold at a particular temperature.
