Relative humidity is a measure of the amount of water vapor in the air. It represents 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 specific temperature, expressed as a percentage.
The ratio of water vapor in a volume of air relative to how much water vapor that volume of air is capable of holding is called relative humidity. It is expressed as a percentage and provides insight into how close the air is to being saturated with water vapor.
Relative humidity expresses the amount of water vapor present in the air as a percentage of the maximum amount of water vapor the air can hold at that temperature. For example, if the relative humidity is 50%, it means the air is holding half of the maximum water vapor it can hold at that temperature.
If a hydrate's vapor pressure is higher than the water vapor in the air, water molecules will evaporate from the hydrate into the air until equilibrium is reached. This process will continue until the vapor pressures are equalized.
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.
Clouds carry large amounts of water vapor. Also, fog and steam carry large amounts of water vapor but is not as large or condence amount.
Water vapor in the air is water in the form of a gas.
it is in science
no one knows
Water vapor enters the air as water at the surface evaporates or as plants transpire water vapor from their leaves.
When water vapor is added to the air, the density of the air decreases. This is because water vapor molecules are less dense than dry air molecules.
The warmer the temperature, the more water vapor in the air. The colder the temperature, the less water vapor in the air.
Water vapor is water is gas form. Humdity is the amount of water the air can hold. So, they're both water in the air.
Relative humidity is a measure of the amount of water vapor in the air. It represents 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 specific temperature, expressed as a percentage.
water vapor
It takes a lot of energy to turn water into water vapor. The amount of energy that the water gains to turn into water vapor begins to be transferred into the surrounding air. If the air is willing to take on more energy the water vapor condenses quicker. This is why hot air will hold more water vapor than cold air.
Saturated air is more dense.
