What weather factor is a hygrometer use for?
Hygrometers measure the relative humidity of the atmosphere. The relative humidity is the ratio between the present water vapor content of the air and the maximum amount of water vapor the air could hold at the same temperature. Cool air will not hold as much water vapor as warmer air. With the same amount of moisture in the air, an increase in temperature decreases the relative humidity, and if the temperature drops, relative humidity increases.
It is a hot summer day with no wind the relative humidity is 50 percent as the sun goes down how would you expect the relative humidity to change?
As the sun goes down, the temperature drops and the capacity to hold water vapor in the air decreases increasing the relative humidity above 0 percent
What is the name for the air that contains water vapor in equilibrium at a certain temperature?
relative humidity
What humidity is measure of the amount of water vapor that air is holding compared to the amount needed for saturation at a specific temperature?
Realative humidity
Relationship between temperature and relative humidity?
If the absolute humidity remains constant while the temperature rises, the relative humidity will decrease (and vice versa). This is because the air's capacity to hold water increases as the temperature increases so the constant amount of water represents a smaller and smaller percentage of the maximum amount the air can hold. A: As air temperature goes up, the maximum amount of water vapor that it can hold goes up. Thus if the water content stays constant, the the humidity goes down. If the humidity stays constant, then the water vapor content goes up.
If the relative humidity is high and the temperature drops water vapor may .?
condense
If the relative humidity is high and the temperature drops water vapor may?
condense
What will happen to the water vapor in the air if the temperature drops as predicted?
When the temperature drops the less water vapor in the air
What will happened to the water vapor in the air if the temperature drops as predicted?
When the temperature drops the less water vapor in the air

What happens to relative humidity as a parcel or air rises?
The relative humidity drops. This is because the temperature for the parcel of air is cold and wet which leaves enough room for some water vapor, but not a lot.
How are humidity and water vapor related?
Relative humidity is directly related to the amount of water vapor in air, and that's the relationship. The more water vapor that is in the air, the higher the relative humidity at a given temperature.
How does humidity change over 24 hours?
Cold air cannot hold as much water vapor as warm air. As temperature drops relative humidity rises. Absolute humidity remains constant until the dewpoint temperature is reached, then decreases with temperature as water precipitates out of the air. Below the dewpoint temperature relative humidity remains constant at 100%.
What is the between humidity and relative humidity?
The ability for the atmosphere to hold water depends on a couple of factors, most notably being temperature. The hotter it is the more water can be absorbed by the air. Absolute humidity then is the total amount of water vapor contained in the air regardless of temperature. Relative humidity is the ratio to the amount of water the air is able to hold at a given temperature compared to the amount of water vapor it currently has (its absolute humidity). Assuming absolute humidity remains the same, and the temperature drops, then relative humidity will go up, meaning if there was already enough water vapor in the air at the previous temperature you might end up sweating more because the lower temperature might not be able to evaporate the same amount of sweat off your body.
Condensation of water vapor in the air occurs when the temperature drops below the point at which the air's?
capacity and specific humidity are the same
Where is water vapor located in the atmosphere?
Dissolved in the air (its humidity) and in clouds as fine drops.
What is the affect of cooling on humidity ratio?
Cooler air cannot hold as much water vapor as the same volume of warmer air, so as the air temperature drops, the relative humidity increases, even when the amount of water vapor in a certain volume of air, or absolute humidity, remains unchanged. If the relative humidity reaches 100%, the air has all the water vapor that it is able to hold. If the temperature continues to drop beyond that point, the excess moisture in the air condenses as dew or frost.
