The boiling point of an element or a substance is the temperature at which the Vapor_pressureof the liquid equals the environmental pressure surrounding the liquid.
if we close the container and change the pressure outside the container.. the boiling point will change... why?? how will the solution inside know that the pressure outside the container is changing and it has to now change its boiling point.??
What else can I help you with?
In What way is the pressure in the atmosphere like the pressure in a liquid?
The pressure in the atmosphere and in a liquid both increase with depth. As you go deeper into the atmosphere or the liquid, there are more air or liquid particles above pushing down, which leads to an increase in pressure. This relationship is described by Pascal's principle.
How does atmosphere pressure vary with altitude?
How does liquid pressure vary with depth
When vapor pressure equals atomospheric pressure what is the liquid?
The Liquid will turn into gas. The boiling point corresponds to the temperature at which the vapor pressure of the liquid equals the atmospheric pressure. If the liquid is open to the atmosphere (that is, not in a sealed vessel), it is not possible to sustain a pressure greater than the atmospheric pressure, because the vapor will simply expand until its pressure equals that of the atmosphere.
Why atmospheric pressure varies with height in a different way from the way liquid pressure varies with depth.?
For the same reason. The liquid above the location considered, or the atmosphere above the position considered, helps contribute to the pressure; if there is more liquid or atmosphere above, there is more pressure.
How does the atmosphere vary with altitude?
How does liquid pressure vary with depth
The temperature at which the vapor pressure of a liquid has an external pressure of 1 ATM is the?
The vapor pressure of a liquid is equal to 1 atmosphere at 100 degrees Celsius, or 212 degrees Fahrenheit. This is because for a liquid to boil, its vapor pressure must rise to reach standard atmospheric pressure, which is about 1 atmosphere. When enough heat is present to do this, the substance will boil.
When vapor pressure equals atmospheric pressure at the surface of a liquid it has reached its what?
When the vapor pressure equals atmospheric pressure at the surface of a liquid, it has reached its boiling point. This is the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on it by the surrounding atmosphere, causing the liquid to change into vapor.
What is the boiling point of a liquid at a pressure of 101.3 kPa?
Each liquid has a different boiling point; 101,3 kPa is he standard atmosphere pressure (atm).
What are the pressure measuring instruments?
a common manometer is a u-tube with a liquid filled about half way in each leg, one end is open to the atmosphere and the other connected to the thing that your measuring the pressure of, as the pressure increases, the liquid in the leg attached to your pressure of interest is forced down, and the pressure in the other leg is pushed up, because you are comparing it to the atmosphere it is a gauge pressure in comparison to the atmosphere =] hope this helps.
How is vapor pressure related to the boiling point?
Vapor pressure is related to the boiling point because the boiling point is the temperature at which the vapor pressure of a liquid equals the atmospheric pressure. When the vapor pressure of a liquid reaches the same pressure as the surrounding atmosphere, the liquid will boil and turn into a gas.
Could water exist as a liquid on Earth if it did not have an atmosphere?
Water could exist as a liquid on Earth without an atmosphere in specific conditions where the temperature and pressure allow for liquid water to form. However, without an atmosphere, these conditions would be less stable and water would be more likely to evaporate or freeze quickly due to the lack of atmospheric pressure and insulation.
Why the liquid boils when its vapor pressure becomes equal to ATM pressure?
When the vapor pressure of a liquid equals the atmospheric pressure, the liquid molecules are escaping the liquid surface as quickly as they are returning, causing the liquid to boil. This is because the vapor pressure represents the point at which the liquid and gas phases are in equilibrium and the liquid can transition to a gas phase.
