A oft-repeated water vapor myth is that warm air can "hold" more water vapor than cool airbecause as the air warms its molecules move farther apart, making room for more molecules. This leads to the idea that as air cools its molecules move closer together, "squeezing" out water vapor.
What else can I help you with?
Can hot air hold more or less water than cold air?
Hot air can hold more water vapor than cold air. This is because warmer air molecules are further apart, allowing more space for water vapor molecules to exist in the air. Conversely, cold air molecules are closer together, limiting the amount of water vapor that can be held.
Why can't cold water hold much more water vapor?
Cold water molecules are closer together, making it difficult for water vapor molecules to fit between them. This limits the amount of water vapor that can be held by cold water compared to warm water. Additionally, the lower kinetic energy and weaker intermolecular forces in cold water result in a lower capacity to hold water vapor.
Does warm air or cold air contain more water vapor?
Quite the opposite. This is why irrigation is recommended overnight instead of during the day. (note: "morning dew") - less water is evaporated during cooler temperatures.
Which holds more water vapor a warm air mass or a cold air mass?
A warm air mass can hold more water vapor than a cold air mass. This is because warm air has a higher capacity to hold moisture due to its higher temperature. When warm air cools down, it reaches its dew point and can no longer hold all the water vapor, leading to condensation and possibly precipitation.
What characteristic allows the troposphere to contain so much water vapor?
The characteristic that allows the troposphere to contain a significant amount of water vapour is its ability to hold moisture through temperature regulation. The warmer the air, the more water vapor it can hold. This is because warm air has a higher capacity to hold water vapor compared to cold air.
Which type of air can hold more water vapor-and-why?
Warm air can hold more water vapor than cold air because warm air molecules have more energy and are more widely spaced, allowing them to accommodate more water vapor molecules. Cold air is denser and has less energy, limiting its capacity to hold water vapor.
Does hot air hold more water vapor than cold air?
Yes.
Can hot air hold more or less water than cold air?
Hot air can hold more water vapor than cold air. This is because warmer air molecules are further apart, allowing more space for water vapor molecules to exist in the air. Conversely, cold air molecules are closer together, limiting the amount of water vapor that can be held.
What holds more water hot air or cold air?
Hot air can hold more water vapor than cold air. As air temperature increases, its ability to hold water vapor also increases due to the increased kinetic energy of the molecules, allowing more water molecules to be suspended in the air. This is why warmer air feels more humid.
Can hot air or cold air hold more water?
warm air hold more water vapor...unless it doesnt like sandwiches between its toes at 5 o'clock in the after noon
Can warm air hold less water vapor than cold air?
no, warm air holds more water vapour than cold air
Why is there a limit on the amount of water vapor the air can hold?
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.
Why can't cold water hold much more water vapor?
Cold water molecules are closer together, making it difficult for water vapor molecules to fit between them. This limits the amount of water vapor that can be held by cold water compared to warm water. Additionally, the lower kinetic energy and weaker intermolecular forces in cold water result in a lower capacity to hold water vapor.
When it's humid the air holds a lot of water vapor but when it's cold what happens to the water vapor?
nothing "happens" 2 the water vapor. the vast amount of water vapor in the air on a humid day as exactly bcoz its so hot. the water is drawn out of sources which holds it. but when its cold that water isn't drawn out
Why does hot air hold more water vapour than cold air?
Because the molecules in the hot air are more spread out, allowing water to easily form within the gaps of the molecules. Cold air is more dense and does not allow water to form easily between the molecules.
Does warm air or cold air contain more water vapor?
Quite the opposite. This is why irrigation is recommended overnight instead of during the day. (note: "morning dew") - less water is evaporated during cooler temperatures.
