Why do divers watches say they are pressurized to three atmospheres?
This basically means that when the diver is underneath the water, the pressure down there is 3 times the pressure at normal land level. This means that the watch won't crack or break at three atmospheres worth of pressure.
Describe the three forms in which water is present in the atmosphere?
evaporation condensation percepataiton
What are three Goldilocks conditions?
The Three Goldilocks conditions are that the temperature is not too hot and not too cold. It is Just Right. If the earth were much hotter, water would be gas-water Vapor. If Earth were much colder, water would be solid Ice.
Can water exist on a planet with no atmosphere?
Atmospheric pressure is an important factor in keeping liquid water on the surface of a planet. With no atmosphere, liquid water would quickly escape into space. It would depend on various factors such as the temperature and escape velocity of the planet of course. Scientists think liquid water existed on Mars in the past when the atmosphere was a lot denser. Water does exist on the surface Mars, but only as ice.
Does the atmosphere cause water level to rise up?
It can do. Winds in the atmosphere cause waves. Also the low pressure in the centre of a depression can cause a elevation in sea level called a storm surge.
Does vapour pressure include the partial pressure of water vapour in the atmosphere during boiling process?
The partial pressure of water (vapor) is included in the total pressure of the atmosphere (air) when boiling.
What does barometric pressure have to do with evaporation?
Above the surface of liquid water is a layer of water vapor. It has pressure. The atmosphere also has pressure. It pushes against the water vapor. The water vapor pushes against the atmosphere. It is called vapor pressure. It is related to temperature. When the vapor pressure equals barometric pressure, water boils. Normally this occurs at 100C or 212F. If you reduce the barometric pressure, you can reduce the boiling point of water. So when the barometric pressure is lower, the water vapor above the water has an easier time mixing with the atmosphere. As it mixes with the atmosphere, it is replaced by vapor from the water. It evaporates.
How deep is 1 atmosphere underwater?
3 cm if you times divide by a number 1 3rd of it depth in cm.
Is Venus' atmosphere mostly water?
Venus' atmosphere is made up mostly of carbon dioxide, it lacks oxygen, and it only has a little nitrogen. Carbon dioxide makes the atmosphere heavy, which makes the atmospheric pressure 90 times stronger than Earth's atmospheric pressure. The atmosphere of Venus is very hot and thick.
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.
How does atmosphere pressure with height in the atmosphere?
Generally, atmospheric pressure is greatest at ground level, because you are at the bottom of the 25 mile thick atmosphere of earth. Greatest water pressure in a swimming pool is at the bottom, too. As you go up into the atmosphere, the pressure tends to decrease.
How does altitude change the boiling point of water?
Water boils when its vapor pressure equals the vapor pressure of the surrounding atmosphere. The atmosphere surrounding the water exerts a pressure, preventing gas molecules escaping from the surface. At higher altitudes, this pressure is much lower so water will boil at a lower temperature.
What happens to water pressure as you move up in the atmosphere?
It increases.
Which fundamental force to pressure in both water and the atmosphere?
gravity
How long does it take for a cup of water to evaporate to three fourths a cup?
This depends on many factors: temperature, pressure, area exposed to atmosphere, etc.
What is the atmosphere pressure at fifty feet in water?
50 feet of water is about 1.475 atmospheres.
What is the boilinge point of water?
The boiling point of water depends on the pressure. At 1 atmosphere pressure, the boiling point is 100ºC or 212ºF.
