By stuffing in many particles inside. It can be water particles, marbles or even air particles. As long as the jar is not vacuum, you can technically say that you have 'pressure in a jar'. However, The usefulness of such statement is questionable as well as the person's understanding of physics.
If the jar was not thick enough to resist the exterior pressure, it would implode, just as a pressurized jar in space would explode.
The balloon exists in a separate pressure system from the bell jar itself.As the balloon is open to the surrounding air, the pressure within the balloon is 1 atm (1 atmospheric unit of pressure = 105 Pa).When pressure is decreased within the jar, the pressure within the jar decreases to a value lower than 1 atm. Therefore, to counter the low pressure created in the jar, the atmospheric air moves into the balloon and pushes the balloon into the jar to attempt to equalize the pressure in the balloon and in the jar. Therefore the balloon inflates.
a water jar is a woven basket used to collect water
Yes you can pressure cook a pint jar in a pressure cooker.
Increase the pressure of the gas inside
Increase the pressure of the gas inside
This depends on the volume and pressure of gas.
Gas jar
They do not.
Jam contains a high proportion of water, so it would depend on the physical strength of the jar. I'm assuming that this is a glass jar? Most likely, the jar would crack or shatter as the pressure around it was decreased, allowing the water in the jam to boil off into the vacuum.
A vacuum in a jar occurs when all air is removed from the jar, creating an absence of pressure. This creates a low-pressure environment inside the jar, which can have various scientific and practical applications like preserving food or conducting experiments that require a controlled atmosphere.
In order for a storm to form there's one thing that's an absolute must-have for it, that would be low atmospheric pressure. Generally the lower the pressure, the more intense a storm can get. The data we can collect ahead of time would be atmospheric pressure data. Atmospheric pressure can be measured in mbs or inHG.
