What is the density of helium at 25 degrees celsius and one atmosphere of pressure?
WATER
How is force being used on a hosepipe?
The forces applied to a hosepipe when the water is turned on is high pressure from the water being stopped in the rubber hose by the nozzle. The force and pressure of the water is pushing out from the inside of the hosepipe.
How does pressure relate to depth?
Pressure = force / area, but > Force (weight) of water = mass * acceleration > Select a depth, choose an area the weight of water is acting on ( say 1 square inch ) calculate the force (weight) of the water column above that area (in pounds) Divide force by area = pressure (pounds per square inch (psi)) Dont forget to add atmospheric pressure (psi) to the answer.
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.
What is the relationship between water depth an pressure?
The depth of water is directly related to the pressure caused by it. It is caused by gravitational force on the amount of water column in the depth.
Which fundamental force contributes to pressure in both water and the atmosphere?

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.
How and why do temperature and pressure vary with ocean depth?
At sea level,the pressure of the atmosphere pushing down on the ocean surface is reffered to as 1 atmosphere of pressure.An atmosphere is the pressure exerted on a surface at sea level by the column of air above it.As you go below the oceans surface ,the pressure increases because of the force of the water molecules pushing down.
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.
A tank with a flat bottom is filled with water to a height of 4 meters What is the pressure at any point at the bottom of the tank?
Pressure is given by the formula -pgh , where p= desity of water , g gravity ,and h height . So pressure at the depth 3.5m =1*9.8*3.5 pa =34.3 pa. (Assuming density of water to be 1).
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.
What is the unit of measurement of presure?
Pressure is Force divided by Area. There are many units commonly used to measure pressure, such as pound-force per square inch (psi) for tyre inflation, Bar (bar) for atmospheric air pressure, meters of water column for bath pressurizers or taps, atmosphere (atm) for underwater pressure etc.. en.wikipedia.org/wiki/Pressure
Is there air pressure in water?
Water is effectively an incompressible substance, so pressure does not affect its' volume. However, its boiling and freezing points are directly related to the external pressure. Water boils when its vapor pressure is equal to the external pressure (or the atmospheric pressure if it is contained in some uncovered pot). Greater external pressure requires higher temperature for water so as to have that value of vapor pressure for it to boil. This is how pressure affects water.
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.
What is the pushing force at the atmosphere is called in the water cycle?
