In an open system the vapor pressure is equal to the outside air pressure?
Yes it is equal
What happens to the pressure inside a container when the temperature of a fluid is increased?
When heated, temperature increases. You may have already guessed that. Most substances, but not all, increase in volume as the temperature increases at constant pressure. The pressure would remain the same if the fluid was in an open container.
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.
If you open a bottle of perfume after a period of time the people on the opposite side of the room will be able to smell it due to the process of what evaporation or vapor pressure?
It is due to diffusion of perfume,it is a sort of evaporation.
Can you calculate absolute pressure using U-tube manometer?
Calculating absolute pressure with a U-tube manometer requires filling it with a non-volatile fluid and sealing one end. The non-sealed end is exposed to whatever fluid you wish to measure the pressure of. The difference in the height of the manometer fluid between the open arm and the sealed arm is an indication of absolute pressure. At zero absolute pressure the fluid should be at the same height in both arms with vacuum above the fluid in the sealed arm. From a practical standpoint, there are no fluids that have zero vapor pressure, but fluids are available with vapor pressures low enough to be negligible compared to the limitations of the ability of the person reading the measurements to read the height of the fluid. As an example, under most operating conditions mercury has a negligible vapor pressure. If you start getting up to high temperatures, however, all bets are off.
In an open system is the vapor pressuse equal to the outside air pressure?
In an open system the vapor pressure is equal to the outside air pressure.
In an open system the vapor pressure is equal to the outside air pressure?
Yes it is equal
Can vapor pressure occur in open container?
Yes. In fact vapor pressure is an important factor in weather.
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 Condensation is not possible in an open vessel?
Wherever in evaporating stream a temperature drops lower, corresponding to lower vapor pressure than the partial pressure of the vapor in the stream, condensation occurs.
Why pressure cooker is closed system?
open system
Why does water boil at a lower temperature on a mountain than sea level?
The boiling of any liquid is tied in to the atmospheric pressure, in an open system. Every liquid has it's own vapor pressure, that is the balance between the vapor and liquid phase. When atmospheric pressure decreases, the vapor pressure increases since now there is greater space for the molecules of the liquid to come into vapor phase. At higher altitudes, the atmospheric pressure is lesser, that is, the air is thinner. Thus the liquid can attain higher vapor pressure faster and boil at a lower temperature.
What is the point at which a liquids vapor pressure equals the atmospheric pressure?
This temperature is called the boiling point, and indicates the temperature at which a liquid will assume a gaseous state, given the addition of the heat of vaporization.That is the boiling point.
What is Siwoloboff method - slide6?
Siwoloboff's method is a method used to establish the boiling point-composition curve of a binary system. It is particularly well adopted for the determination of boiling points of small samples of pure liquids and of mixtures. In this method, the open end of a short capillary tube (sealed at the other end) is immersed in the liquid under investigation. The tube serves as a manometer to determine the temperature at which the vapor pressure ofthe liquid is equal to the pressure of the atmosphere (boiling point definition)
What happens to the pressure inside a container when the temperature of a fluid is increased?
When heated, temperature increases. You may have already guessed that. Most substances, but not all, increase in volume as the temperature increases at constant pressure. The pressure would remain the same if the fluid was in an open container.
Difference between set pressure and blow-off pressure?
The set pressure is the pressure at which a relief valve starts to open. When the valve is open and relieving, the pressure will be higher or lower than the set pressure, depending on the system and the valve design. That is the blow-off pressure.
What is the difference between open cup and closed cup flash point?
The fuel sample in the open cup is exposed to air,thereby decreasing it's vapor pressure when compared to the same in a closed cup.
