If Mars did have liquid water at one time what happened to it and why?
One popular theory is that when mars lost its atmosphere, the liquid water evaporated into space.
What planet's atmosphere has no air or water?
Mercury is the only major planet without an atmosphere. It is able to hold some gases close to its surface, but not really enough to call it an atmosphere. Its due to the size of the planet being so small and lack of a decent magnetic field that it is unable to sustain an atmosphere.
Is water vapour not one of the constituents in air?
Water vapour is a constituents in air because water vapour rises in the atmosphere & is always present in the atmospere in some or the other quantity.Also 0.0001% of air consist water vapour
Does Jupiter have water?
Jupiter has very little water (0.0004%).There is no LIQUID water on Jupiter because Jupiter is a gas giant. However, Jupiter DOES have evaporated water in its atmosphere and one of its moons, Europa, is said to have a frozen ocean on its surface.
Which planets have no atmosphere?
Mercury is the smallest of the eight planets, and is the only one not to have an atmosphere. This is due to its small size and close proximity to the sun.
What is the equivalent depth of one atmosphere in the ocean equal to in fresh water and sea water?
33 feet in sea water, 34 feet in fresh water
What depth equals 20 bar?
One Bar is 10.2 Meters of fresh water or 9.0 meters of saltwater. it is 204 meters for fresh water. and 180 meters in salt water. :-)
How deep in the water is one atmosphere?
4 atmospheres is about 135.6 feet of water depth.
How many feet in fresh water equals one atmosphere?
33 feet
How does the salinity of the ocean change with depth?
The concentration of Saline [solution] at depth depends upon, for one thing, the degree of presence of [newly introduced in this case] fresh Water.
What is the pressure of ocean water at sea level?
Right at the surface of the ocean, the pressure is just the same as the air pressure at sea level; that is, one "atmosphere", or about 14.7 PSI (Pounds per Square Inch). But water pressure increases with increasing depth: For each foot of depth, the water pressure increases by 0.445 PSI. SCUBA divers, who need to be very aware their depth because of this pressure effect, often use this rule: Every 33 feet of depth, water pressure increases by one "atmosphere" (14.7 PSI). So, for example, at 66 feet the pressure on a diver is three atmospheres: There's one atmosphere of pressure from the air, and two atmospheres from the water.
20BAR what is this measurement aquatic?
You question is not clear, but I think you mean to ask how deep in water is a pressure of 20 Bars. A bar is one atmosphere pressure which is about 10 meters of water depth. Since water is incompressible, the relationship is linear. 20 Bars is 200 meters depth.
One way that fresh water and ocean water are alike?
because fresh water is good
Pressure increases with depth by adding one atmosphere of pressure for every how many meters?
10
What happens to potatoes in fresh water and salt water?
In fresh water it will swell in salty one it will shrink
Can you swim with a 5 ATM wach?
Yes, unless you are diving to a rather deep depth. One atmosphere is 15 pounds per square inch (or PSI.) A 5 ATM watch should be resistant to water entrainment to a pressure of 15*5, or 75 PSI. That would correspond to a depth of approximately 150 feet, depending on whether you are in fresh or salt water. Watch out, though - many watches not designed for diving have leather or other types of bands that can be damaged by water, especially salt water. (Anything you wear in salt water should be thoroughly rinsed afterwards to get rid of sea salts.)
Are x-ray fish salt-water or fresh-water fish?
fresh, its a tetra if its this one
