What else can I help you with?
Are there many of air molecules inside a vacuum?
No, a vacuum by definition is a space with no air molecules present. Therefore, there are no air molecules inside a vacuum.
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.
How is the air pressure inside the jar related to the air molecules inside the jar?
The air pressure inside a jar is related to the number of air molecules present. When there are more air molecules in the jar, the pressure increases due to more collisions with the walls of the jar. Conversely, fewer air molecules result in lower pressure.
How could you increase the air pressure inside a bag containing a group of air molecules?
You could increase the air pressure inside a bag by decreasing the volume of the bag, adding more air molecules to the bag, or increasing the temperature of the air molecules inside the bag.
What causes the suction of a vacuum?
The suction of a vacuum is caused by a difference in air pressure inside the vacuum cleaner compared to outside. A motor creates a low-pressure zone inside the vacuum, causing the higher-pressure air outside to push debris into the vacuum cleaner.
Are there many of air molecules inside a vacuum?
No, a vacuum by definition is a space with no air molecules present. Therefore, there are no air molecules inside 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.

Why sound is not transmitted to a vacuum?
What we hear as sound is caused by pressure waves in the air which make small hairs deep inside our ears vibrate. Since there is no air or anything at all inside of a vacuum, there are no molecules to bump into each other to transfer the pressure wave through space.
What causes your lungs to pull in air from the atmosphere?
By expanding them, you create a vacuum inside them; given a portal (your mouth, nose), the vacuum will pull the ambient air in, just as a vacuum cleaner pulls things inside by creating a vacuum.
How is the air pressure inside the jar related to the air molecules inside the jar?
The air pressure inside a jar is related to the number of air molecules present. When there are more air molecules in the jar, the pressure increases due to more collisions with the walls of the jar. Conversely, fewer air molecules result in lower pressure.

What is a machine that contains no particles or molecules inside of it?
There is none, but its approximated by a vacuum pump.
What causes the suction of a vacuum?
The suction of a vacuum is caused by a difference in air pressure inside the vacuum cleaner compared to outside. A motor creates a low-pressure zone inside the vacuum, causing the higher-pressure air outside to push debris into the vacuum cleaner.
How is air pressure used in a vacuum cleaner?
Air pressure is used in a vacuum cleaner to create suction. The motor inside the vacuum cleaner generates a lower air pressure inside the machine, causing outside air to rush in with force through the nozzle. This rapid movement of air allows the vacuum to pick up dirt and debris from surfaces.
How does a can crush when you heat up the air inside then let it cool?
When you heat up the air inside a can, the molecules gain kinetic energy and move faster, increasing the pressure inside the can. When you quickly cool the can by submerging it in cold water, the air molecules lose energy and slow down, causing a decrease in pressure inside the can. The external atmospheric pressure then crushes the can as it is now greater than the pressure inside the can, resulting in the can collapsing.
Why electron travel through the vacuum and not travel through the air?
Electrons can travel through a vacuum because there are no atoms or molecules to collide with, allowing them to move freely. In air, electrons collide with the molecules present, which disrupts their movement and prevents them from traveling efficiently.
