When all the liquid has evaporated the vapor totally fills the florence flask and exerts a pressure equal to the atmospheric pressure why?
I'm guessing you are analyzing an experiment where you are determining the molecular mass of an organic liquid. You heated the flask and the liquid evaporated filling the flask, but escaping through a small hole in the covering.
1. Gases always fill the container. So, if the liquid evaporated and formed a gas (vapor), it filled the flask,
2. The pressure on the outside the flask is air pressure. since the vapor isn't pushing off the cover, the pressure is not higher than the air pressure. But since the extra escaped, it cannot be less than the air pressure. Therefore, it is the same.
What else can I help you with?
What kind of liquid pressure is exerted at equilibrium and is dependent on temperature only?
vapor-novanet.who ever answered dhis is totally awesome.. i gotta agree. saved my butt
1 lbs pressure is how much psi?
The acronym PSI stands for "Pounds per Square Inch," and is the common unit of measurement for pressure. It can be understood as the amount of force that is exerted on an area of one square inch. Normal atmospheric pressure at sea level is 14.7 PSI The acronym PSI stands for "Pounds per Square Inch," and is the common unit of measurement for pressure. It can be understood as the amount of force that is exerted on an area of one square inch. Normal atmospheric pressure at sea level is 14.7 PSI
How are rain and water vapor different?
Water vapor is totally invisible. If you see a cloud, fog, or mist, these are all liquid water, not water vapor.Water vapor is extremely important to the weather and climate. Without it, there would be no clouds or rain or snow, since all of these require water vapor in order to form. All of the water vapor that evaporates from the surface of the Earth eventually returns as precipitation - rain or snow.When liquid water is evaporated to form water vapor, heat is absorbed. This helps to cool the surface of the Earth. This "latent heat of condensation" is released again when the water vapor condenses to form cloud water. This source of heat helps drive the updrafts in clouds and precipitation systems, which then causes even more water vapor to condense into cloud, and more cloud water and ice to form precipitation.
What is the name for a space that contains no air?
A totally empty space (containing neither air nor anything else) is called a vaccum.
How does the air pressure affect how far a Soccer ball will travel?
Air pressure affects how far a soccer ball will travel by impacting its overall density and elasticity. When a soccer ball is properly inflated to the recommended air pressure, it will have the ideal balance of firmness and bounce, allowing it to travel further when kicked. If the air pressure is too low, the ball will be less responsive and may not travel as far due to increased drag and reduced energy transfer upon impact. Conversely, if the air pressure is too high, the ball may be overly rigid and difficult to control, resulting in shorter distances traveled.
Why do scientist us barometers?
They use barometers to measure the atmospheric pressure. The lower the pressure the more likely there is weather coming. The higher the air pressure the more likely the skies will either become mostly sunny or totally clear off and bring sunny skies.
What result would be expected if a salt solution for 2 days?
The water is partially or totally evaporated, depending on the solution concentration.
What is atmospheric pressure on the top of a wing in flight?
That totally varies based on the angle of the wing and air speed of the wing. It will typically be considerably less then normal atmospheric pressure.More Information:The atmospheric pressure on a wing in flight is subject to many variables and is difficult to assess. It varies, mostly due to wing shape and angle, and air speed. The important thing is that the pressure on the bottom of the wing is greater than the pressure on the top. This pressure differential results from the shape and angle of the wing, and the air flow across it. However, regardless of how this pressure differential is generated, it is called lift, and it's what makes flight possible. For example, as an airplane moves down the runway for take-off, it generates more and more lift as its speed increases. When the lift is sufficient to overcome gravity and friction (drag), flight happens.
What is the principle of boiling point?
The boiling point is the temperature at which a liquid changes from a liquid to a gas. It is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure. Substances with higher boiling points require more energy to convert from a liquid to a gas.
Is zyatonix bad for highblood pressure?
I love donuts when they are totally crispy. Donuts Rule!
Why doesn't air pressure crush human beings standing at sea level?
Humans are adapted to the air pressure at sea level, which exerts a balanced force on our bodies from both the outside and inside. Our bodies are able to withstand this pressure due to the internal air pockets in our lungs, ears, and sinuses adjusting to match the external pressure. As a result, there is no net force acting on our bodies that would cause us to be crushed.
Which explains the relationship between the gas pressure gradient of the atmosphere and the alveolar air that allows inhalation?
Sub atmospheric pressure in the lungs is generated through sudden expansion caused by the diaphragm and accessory muscles; this sudden and brief pressure gradient is recognized by airflow from the atmosphere into the lungs until they are filled. Once the lungs are filled and achieve a greater than atmospheric pressure another pressure gradient is established and with the assistance of elastic recoil allow exhalation to occur. This end of exhalation provides a temporary period of equilibrium between the lung and outside atmosphere where no air flow occurs. The lungs never totally deflate. The remaining volume left in the lungs after passive exhalation is referred to as the Functional Residual Capacity or FRC. A person can forcefully exhale a portion of their FRC but cannot eliminate all of it; a remaining portion referred to as the residual volume remains. A combination of factors involving surface tension of the alveoli and 0 pressure gradient prevent the elimination of RV.
Can I use evaporated milk In cereal?
Oh, dude, you can totally use evaporated milk in cereal! It's like regular milk, just less... watery. So, go ahead and pour that creamy goodness over your cereal and enjoy your breakfast in style. Just remember, it's not going to evaporate in your bowl or anything, so no disappearing acts here!
Does pressure gauges have electronic parts?
There are different kinds of sensors and guages which measure pressure. The first ones were mechanical. The next generation were a combination of mechanical and electrical parts, and now, some pressure detecting systems have no moving parts, and are totally electronic.
What is the song rabbit heart about?
I tink i could be wrong but looks like (florence and the machines rabbit heart) is about having to sacrafice somthing but been afraid of sacraficing it and saying she has to be brave about it, or i could be totally wrong :/ :) tash :)
Is 137 60 high or low blood pressure?
It totally depends on your age. Regarding your age of 50, a blood pressure of 136/60 mm Hg is normal.
How much pressure can a submarine withstand?
It's totally dependent on the hull type, material construction, and overall design, but in general, just before a submarine reaches crush depth is as much sea pressure as it can handle.
