Why breathed-out air turns time water cloudy quicker than breathed-in air?
breathed out air turns lime water cloudy than breathed out air cuz the carbon dioxide content present in breathed out air(0.04% approximately) as compared to breathed out air(4% approximately)so as CO2 passes through lime water it turns lime water cloudy:)
Ice cubes form in the freezer because?
The freezer takes heat out of the air in it, and discards the heat elsewhere. As long as the air in the freezer is colder than the water in the ice-cube tray, heat flows out of the water into the air around it, and is removed by the freezer. If the temperature of that air happens to be lower than the melting/freezing point of water, then the water eventually freezes at some time during the process.
How do you desalt salt water by freezing?
Because water wants to freeze in it's pure form, you can spray water into cold air. As the water begins to freeze in the air, the salt is pushed out. By the time it lands, the frozen water is pure and since some of the water contains all the salt, it drains off. The ice that is left is de-salted.
Compare the density of water and air?
Air's density is less than that of water. Water's density is almost 800 times greater than air.
Why does water in lake evaporate?
During the day time all the air surrounding us gets heated. The warm air provides heat for evaporation of water in shade. Thus,evaporation takes place from all open surfaces of water . Water vapour gets continuously added to air . evaporation of water is a slow process.
What is the residence time of water in the atmosphere?
.024 years or nine days
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 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.
What is the formula for calculating residence time?
the hydraulic residence time t is given by t=V/q where V is the volume in the tank and q is the volumetric flow rate. A theoretical residence time can be given by the relationship between concentration and time ln(C)=-(t/tav) where tav in this equation is the residence time.
How does water get to the atmosphere?
it evaporates into the air over time.
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.
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 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...
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 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.
