vurtually no molecules will be in the container... and great force will be put on the walls of the container

Would you consider atmospheric pressure when finding the pressure of a liquid in a closed container?
pressure is usually measured relative to atmospheric this is called gauge pressure. if you compare against absolute zero pressure (vacuum) this is called absolute pressure.
What is the pressure of a container that has a vacuum inside of it?
Since there's no particles present, there's no pressure.
If the pressure in a sealed container is reduced can boiling point of a fluid be also reduced?
Yes. You can, for example, boil water at room temperature if you apply a vacuum pump to the container. However, if it was ONLY a sealed container (reduce the pressure and then take the vacuum pump away), the vapor increases the pressure and the whole thing comes to equilibrium and stops boiling.
Why is there no gas pressure inside a vacuum?
Gas pressure is caused by the molecules of gas striking the walls of a container, or in the case of Earth's atmosphere, the molecules of air hitting the earth. In a vacuum, there are no gas molecules. No molecules, no pressure.
Why does Mercury stay in the barometer?
A barometer is a closed-system vacuum that allows the mercury to expand with changes in temperature and pressure.
What component is closed during charging to prevent the flow of refrigerant to the low-pressure side of the refrigeration system?
The King valve is closed, starving the low pressure side, creating more vacuum while charging with a liquid
What is the operating principle of vacuum evaporator?
When a solution in a closed container reaches its max vapour pressure, that means that there are particles evaporating at the same rate they are dissolving back into solution from the gas sample above. When this point of equilibrium is reached, the volume of liquid in solution will no longer reduce. By creating a vacuum above the liquid, the vapour pressure becomes 0kPa (or at least very low). This keeps the particles in the gas from dissolving back into the solution, well, because there is no more gas! It's a vacuum!
How can make a vacuum in glass?
A vacuum can be produce by emptying a container
What is a vacuum breaker?
A vacuum breaker is a mechnical device used to avoid backflow or a negative pressure in a plumbing system. It typically consists of an air valve with a spring holding it closed. When the pressure within the system is positive, the valve remains closed. When the pressure is negative (less than atmospheric), the negative pressure overcomes the force of the spring holding the valve closed and the it opens, typically allowing normal atmospheric air to enter the system, thereby eliminating the negative pressure. Otherwise, the negative pressure might cause backflow of the plumbing system. ...
Why does water boil in a vacuum?
Clarification: I am wanting to know how much vacuum I need to pull to get water to boil at 150 degrees.
What is vacuum integrity?
Vacuum decay can be inspected through seal integrity testing and container integrity testing. It checks for leaks in the container that require a minimum vacuum level.
How many inches of vacuum equals 10 mm of hg?
