When the water level is higher inside than outside the flask is the gas pressure in the flask higher or lower or the same as the atmospheric pressure?
When the water level is higher inside the flask than outside, the gas pressure in the flask would be lower than the atmospheric pressure. This is because the water exerts a partial vacuum on the gas in the flask, reducing its pressure compared to the external atmospheric pressure.
Why would water boil at less than 100 degrees on top of a mountain?
The boiling point of any liquid is the temperature at which its vapor pressure becomes equal to the atmospheric pressure. So if the atmospheric pressure is lower, it will take a lower temperature to make the vapor pressure equal to that of atmospheric pressure. At hill-stations, the air is generally thinner due to the altitude and the atmospheric pressure is also lower. Here, it requires less than 100oC temperature to reach the point where the vapor pressure of water reaches that of air. So, water boils below 100oC at hill stations.
In the Fahrenheit temperature scale what is the boiling point of water?
In atmospheric pressure (ie at sea level), water boils at 100 degrees Celsius.
A barometer is an instrument used for measuring water pressure?
otherwise know as a barometer and it measures air pressure in newtons
What is the total pressure gauge pressure plus atmospheric pressure?
Total pressure is equal to the sum of gauge pressure and atmospheric pressure. Atmospheric pressure is always present and contributes to the total pressure measurement.
What are the different types of pressure feet?
water for example.absolute pressure; gauge pressure; atmospheric pressure
Why is it different at 5000 feet to boil water?
The atmospheric pressure is lower. When you are boiling the water, the water's vapour saturation pressure is able to match the atmospheric pressure faster therefore it boils faster and at a lower temperature.
You are collecting gas over H2O in an experiment does the atmospheric pressure have anything to do with the pressure inside the gas collection container?
Yes, the pressure inside the collection container will be exactly equal to the atmospheric pressure if the water level in the collection container is level with the rest of the water. If the atmospheric pressure is different, then the pressure inside the collection container will be different, and that will affect how you calculate the amount of gas collected. If the pressure is different due to the difference in altitude of the location, or even different weather, the results will be different. Simply measuring the atmospheric pressure with a barometer will allow you correct for any such differences.
How is evaporation different from boiling?
as the evaporation occurs under the atmospheric pressure that is492degr and the boiling point occurs above the atmospheric pressure different liquids have different boiling points just the boiling point of water is 100deg c
How do you calculate total pressure of water?
The total pressure of water is calculated by adding the atmospheric pressure to the pressure due to the depth of the water column using the formula: total pressure = atmospheric pressure + (density of water × acceleration due to gravity × depth of water).
Will the boiling point of water differ different with noon temperature?
Different places have different elevation, and different elevations have different air pressure. It is the ambient air pressure which affects the boiling point of water. Air presses down on water, making it harder for the water to form bubbles. Less pressure produces a lower boiling point. More pressure produces a higher boiling point.
What is the saturation temperature of water at standard atmospheric pressure?
The saturation temperature of water at standard atmospheric pressure is 100 degrees Celsius.
What are different types of pressure sensors?
absolute pressure; gauge pressure; atmospheric pressure...
Why is the boiling point of water different in San Diego than in Utah?
The boiling point of water depends on the purity of the water as well as the atmospheric pressure.
What is the difference between atmosphere pressure and water pressure?
Atmospheric pressure is the pressure exerted by the weight of the atmosphere above a given point, while water pressure is the force exerted by water on an object or surface due to the depth of the water. Atmospheric pressure decreases with altitude, while water pressure increases with depth.
What happens when pressure greater than atmospheric pressure is applied to pure water or a solution?
When pressure greater than atmospheric pressure is applied to pure water or a solution, the boiling point of the water/solution will increase. This means that the liquid will need to reach a higher temperature before it boils. Conversely, if the pressure decreases below atmospheric pressure, the boiling point will decrease, requiring a lower temperature for boiling to occur.
What is cause of atmospheric pressure?
Just as water pressure is caused by the weight of water, atmospheric pressure is caused by the weight of the air. Pg. 126 Conceptual Physical Science 4th Edition.
