100% if it is completely saturated.
what is the relative humidity of air that holds all the water it can
Relative humidity is a measure of the amount of water vapor present in the air compared to the maximum amount of water vapor that could be present at a given temperature. It is expressed as a percentage, with 100% relative humidity meaning the air is saturated with moisture.
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.
No, humidity and relative humidity are not the same. Humidity refers to the amount of water vapor in the air, while relative humidity is a measure of the amount of water vapor present in the air compared to the maximum amount the air can hold at a specific temperature.
When a parcel of air is saturated with water vapor the relative humidity of that parcel of air is 100%.
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.
Relative humidity is relative to the air temperature, so it can change even if the amount of water vapor stays the same. It doesn't give a full picture of the amount of water vapor present because cold air can hold less water vapor than warm air, making relative humidity misleading in terms of actual moisture content in the air.
Relative Humidity is actually measure the amount of moisture in the air. It depends on how much of the air has water in it. Let's say that the RH is 50%, that means 50% of the air has water in it.
If water vapor is removed from the air, the relative humidity decreases. Relative humidity is a measure of the current amount of water vapor in the air compared to the maximum amount the air can hold at a given temperature. With less water vapor present, the air becomes drier, leading to a lower relative humidity percentage.
Relative humidity changes with temperature and amount of water vapor in the air. As temperature increases, air can hold more water vapor, resulting in a decrease in relative humidity. Conversely, as temperature decreases, relative humidity increases as the air becomes saturated with water vapor.
Because it is relative to temperature!
Humidity refers to the amount of water vapor in the air, while relative humidity is the ratio of the amount of water vapor present in the air to the maximum amount of water vapor the air can hold at a given temperature.
