How do you calculate the residence time of water in a given system?
To calculate the residence time of water in a system, you divide the total volume of water in the system by the rate at which water enters or exits the system. This gives you the average amount of time a water molecule stays in the system before leaving.
How do you calculate the residence time of water in a lake?
The residence time of water in a lake is calculated by dividing the volume of water in the lake by the rate at which water flows into or out of the lake. This helps determine how long water typically stays in the lake before being replaced.
How much of the earth's total water is tied up in the atmosphere?
Approximately 0.001% of Earth's total water is stored in the atmosphere as water vapor at any given time.
What may have oceans to form as Earth's atmosphere changed?
Oceans formed on Earth as its atmosphere cooled and water vapor in the atmosphere condensed into liquid water, which then collected in low-lying areas to form bodies of water. Over time, continuous rainfall helped to fill these bodies of water, eventually forming oceans.
How much of earths water is stored in the atmosphere?
Less than 0.001% of Earth's total water supply is stored in the atmosphere at any one time. This includes water vapor, clouds, and precipitation. The vast majority of Earth's water is found in the oceans.
What is the residence time of water in air?
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.
If the total mass of N2 in the atmosphere is 3.87e21 grams or 2.901 moles based on the denitrification rate of 310e12 grams year what is the residence time of N2 in the atmosphere?
Residence time = 3.87E21/310E12 = 1.25E7 years
Which has the longest residence time on continents?
Methane has the longest residence time on continents among the greenhouse gases, due to its lower reactivity and slower rate of removal from the atmosphere.
What are the residence times of the major greenhouse gases?
The residence times of major greenhouse gases vary significantly. Carbon dioxide (CO2) can remain in the atmosphere for hundreds to thousands of years, while methane (CH4) has a shorter residence time of about 12 years. Nitrous oxide (N2O) stays in the atmosphere for approximately 114 years. Water vapor, while a potent greenhouse gas, has a much shorter residence time, typically lasting only a few days to weeks due to its rapid cycle through evaporation and precipitation.
What is residence time of CO2?
Residence time of CO2 refers to the average amount of time a molecule of CO2 remains in the Earth's atmosphere before being removed by natural processes. It is estimated to be around 4 to 5 years.
How do you calculate the residence time of water in a given system?
To calculate the residence time of water in a system, you divide the total volume of water in the system by the rate at which water enters or exits the system. This gives you the average amount of time a water molecule stays in the system before leaving.
How do you calculate the residence time of water in a lake?
The residence time of water in a lake is calculated by dividing the volume of water in the lake by the rate at which water flows into or out of the lake. This helps determine how long water typically stays in the lake before being replaced.
What is the average residence time of a molecule of water?
The average residence time of a molecule of water in the Earth's hydrosphere varies depending on its location. In the oceans, it can be around 3,000 years, while in glaciers and ice caps, it may be tens of thousands of years. In rivers and lakes, the residence time is much shorter, often just days to months. Overall, the average residence time across all water bodies is estimated to be about 2,500 years.
Do chemicals have the shortest average residence time in the biosphere lithosphere hydrosphere or atmosphere?
Chemicals generally have the shortest average residence time in the atmosphere. This is because they can be quickly dispersed or degraded by various atmospheric processes such as photolysis and chemical reactions. In comparison, chemicals may reside longer in the biosphere, hydrosphere, or lithosphere depending on their properties and interactions with the environment.
What sphere do chemicals have the shortest average residence time?
Chemicals typically have the shortest average residence time in the atmosphere. This is due to the rapid processes of chemical reactions, precipitation, and atmospheric transport that can quickly remove substances from the air. In contrast, chemicals tend to reside longer in other spheres like the lithosphere or hydrosphere, where processes such as soil absorption or water movement can prolong their presence.
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..
