The residence time of water in air is typically around 9 days. This means that, on average, a water molecule will remain in the atmosphere for about 9 days before either being deposited back onto the Earth's surface as precipitation or being absorbed by vegetation.

Why breathed-out air turns time water cloudy quicker than breathed-in air?
Breathed-out air contains higher levels of moisture, heat, and carbon dioxide compared to breathed-in air. This combination creates a favorable environment for bacteria to grow faster, leading to quicker clouding of the water.
What is the residence time of sodium in millions of years if the total amount of sodium in the oceans is 1.5x1022g and it supplies to the ocean at a rate of 2.2 x 1014 grams per year?
The residence time of sodium in the oceans is calculated by dividing the total amount of sodium in the oceans by the rate at which it is supplied. In this case, the residence time of sodium in millions of years would be (1.5x10^22 g) / (2.2x10^14 g/year) = 6.8x10^7 years.
Does silver react with water?
Silver does not react with water at room temperature. However, over time, silver may react with water and oxygen in the air to form a thin layer of tarnish.
How do you prove air is in water?
One way to prove that air is in water is to observe the formation of bubbles when water is agitated or heated. These bubbles are composed of air that was dissolved in the water. Another method is to measure the oxygen or nitrogen content in water, which indicates the presence of air.
Compare the density of water and air?
Water is denser than air. The density of water is about 1000 kg/m^3, while the density of air at sea level is about 1.2 kg/m^3. This is why objects float in water but fall in air.
What is the residence time of water in the atmosphere?
The residence time of water in the atmosphere is around 9 days on average. This means that water molecules remain in the atmosphere for about 9 days before returning to Earth as precipitation.
Residence time of water molecule in the ocean is---?
Residence time of water molecule in the ocean is estimated to be 3000 years. This answer is wrong because this question was asked in exam for the post of junior engineer and the options were- a) 3.5 year b) 3.5 million years c) 35 years d) 35000 years So answer is one from the above..
Can you purchase water credits in pebble beach for a home residence?
I believe you can but only for a limited time.
How are inputs outputs residence time and recharge related to aquifers?
inputs help aquafy the water outputs release the water from the aquifer
What is the formula for calculating residence time?
The formula for calculating residence time is: Residence time = Volume of the system / Flow rate of the system. This formula helps in determining the average amount of time a substance will spend in a system or a reactor.
What is residence time of gas?
Residence time in the boiler is typically two to five seconds, and the particles must be small enough for complete combustion to have taken place during this time. The ratio of gas occupied to a particular volume is called residence time based on gas.
What is Difference between residence time and space time?
Residence time is the time it takes a particle to complete the cycle. Space time is volume of the reactor over the velocity. If the volume does not change and the velocity remains constant then Residence time = space time, however, if there is a disturbance in the reactor (i.e., change in pressure, temp, ect.), then residence time does not equal to space time.
How does water get to the atmosphere?
it evaporates into the air over time.
What was Aphrodite's residence?
Cyprus/ Kypros - the island of Love and Beauty! Check it out...it is still today has an intoxicating scent in the air...I love Cyprus, and it is said that is where she came out of the water and loved and played...
Why does the quantity of water decrease in a tumbler when it is exposed to air for a long time?
When water is exposed to air at ordinary temperature and humidity it evaporates. That is, molecules of water leave the liquid and mix with the air.
Average residence time?
The average residence time is a measure of the time it takes for the total stock or supply of the material to be cycled through a system. To compute the average residence time (T; assuming constant size of the system and constant rate of transfer), we take the total size of the stock (S) and divide it by the average rate of transfer (F) through the system: T=S/F. Example if a reservoir holds 100 million cubic meters of water, and both the average input from streams entering the reservoir and the average output over the spillway are 1 cubic meter per second, then the average residence time for a cubic meter of water in the reservoir is 100 million seconds, or about 3.2 years.
Which type of pesticide has the longest residence time in the environment?
Organochlorine pesticides, such as DDT, have been known to have a long residence time in the environment. These compounds are resistant to breaking down and can persist in soil, water, and organisms for many years, causing potential harm to ecosystems and human health.
