The heat index can be calculated when the air temperature is greater then 80F and the relative humidity is at least 40%.

What term is defined as the amount of water vapor in the air compared to the amount of water that the air can hold?

This is the measure of relative humidity. At 50 percent relative humidity, the air is holding half of what it could. It is relative humidity because it is related to the temperature and pressure of the air.


What is the relative humidity of air filled to half its capacity?

Relative humidity becomes the ratio between the actual amount of water vapor present to the capacity that the air has at a particular moment. Just to be an optimist, if the glass is half-filled, the relative humidity is 50 percent. If the glass is three-quarters filled, the relative humidity is 75 percent.


What is the percent of relative humidity when raining?

Relative humidity can vary during rain, depending on factors such as temperature and amount of precipitation. Generally, during rain, relative humidity tends to be close to 100% due to the presence of moisture in the air from the rain.


Is air with 100 percent relative humidty said to be dry?

No, air with 100 percent relative humidity is not considered dry. It means that the air is holding the maximum amount of water vapor it can hold at that temperature, making it saturated. Dry air would have a lower relative humidity percentage.


What is the percentage of humidity?

The percentage of humidity represents the amount of water vapor present in the air compared to the maximum amount it could hold at that temperature. Humidity levels can vary depending on location, weather conditions, and time of day.

What is the measure of water vapor in the air compared to the amount could be held at a specific temperature?

This is the measure of relative humidity. At 50 percent relative humidity, the air is holding half of what it could. It is relative humidity because it is related to the temperature and pressure of the air.

What is the relative humidity when the dry-bulb temperature is C and the wet bulb temperature is C?

50 percent


When the relative humidity is 100 percent the air temperature is equal to the dew point temperature?

Yes, when the relative humidity is 100 percent, it means the air is holding the maximum amount of moisture it can at that temperature. At this point, the air temperature is equal to the dew point temperature, causing condensation to form as the air becomes saturated with moisture.


If the relative humidity is 90 percent does that mean there is only 10 percent of air left?

No, relative humidity refers to the amount of water vapor in the air compared to the maximum amount it can hold at that temperature. A relative humidity of 90% means the air is holding 90% of the maximum water vapor it can hold at that temperature, not that only 10% of the air is left.


What does it mean if the relative humitiy is 79 percent?

Relative humidity is the amount of moisture in the air compared to what the air can hold at that temperature - so to fully explain, we need to know the temperature


How do use the word relative humidity in a sentence?

Relative humidity means the percentage of water vapor in the air compared to the total amount that could be contained. Or the measure of the amount of water vapor that air is holding compared to the amount it can hold at a specific temperature. This is different at different temperatures. Here are a couple of sentences:1. The relative humidity is 10 percent.2. We studied relative humidity in class.3. Saturation air has a relative humidity of 100 percent.

What does it mean when humidity is 100 percent?

This is called relative humidity. It is the ratio between the actual humidity, and the humidity for saturated air - that is, the maximum amount of water air can hold. This saturation point is dependent on temperature.


What type of air has a realative humidity of 100 percent?

That would be "dewpoint"...When the air temperature falls to the dewpoint (or dewpoint rises to the air temperature), then you have 100% relative humidity.


If you have measured the temperature of the air and have found it to be 75o F with 80 percent relative humidity If the amount of water vapor that was contained in the air at that time does not change?

If the amount of water vapor in the air does not change, the relative humidity will remain at 80% as long as the temperature remains constant at 75°F. If the temperature changes, the relative humidity will change, as it is dependent on both temperature and the amount of water vapor in the air.
