What is the pressure of a container that has a vacuum inside of it?
Since there's no particles present, there's no pressure.
How the vacuum is created?
A vacuum is created by removing air or any other gas from a closed container, resulting in low pressure relative to the surrounding atmosphere. This can be achieved using a vacuum pump, which removes gas molecules from the container, creating a space where there are fewer air molecules present.
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.
How can make a vacuum in glass?
To create a vacuum in a glass container, you can use a vacuum pump to remove air molecules from within the container. Place the glass container on a vacuum pump, turn it on to create a low-pressure environment, and then seal the container to maintain the vacuum inside. This will remove most of the air molecules from the container, creating a vacuum.
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.
How is a vacuum achieved?
A vacuum is achieved by removing all gases and creating a space with minimal or no air pressure. This can be done using vacuum pumps to pump out the air molecules from a container, creating a low-pressure environment.
Why will a container impload?
A container will implode when the pressure inside it drops significantly below the pressure outside. This can occur if the container is subjected to a vacuum or if the contents rapidly cool, causing a decrease in internal pressure. The external atmospheric pressure then crushes the container, leading to implosion. Factors like structural integrity and material properties also play a role in determining whether a container can withstand such conditions.
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.
Can you use a compressor to create vacuum?
No, compressors are designed to increase pressure by reducing volume, not create a vacuum by removing air. To create a vacuum, a dedicated vacuum pump is required which operates by removing air from a closed system.
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.
Can Tupperware containers that are vacuum sealed be safely used in the microwave?
No, Tupperware containers that are vacuum sealed should not be used in the microwave as the vacuum seal can create pressure and cause the container to explode. It is not safe to microwave vacuum-sealed Tupperware containers.
Why empty get stuck to mouth when it is sucked?
Empty containers can get stuck to the mouth when sucked due to the creation of a vacuum within the container, causing external air pressure to push the container against the mouth. The negative pressure inside the container keeps it firmly in place until the seal is broken.
