vacuum pressure

Vacuum pressure refers to the force exerted by the absence of air or gases in a space, compared to atmospheric pressure. When we create a vacuum, we're removing air molecules, resulting in pressure lower than normal atmospheric levels. This difference in pressure can be useful in various applications such as packaging, scientific experiments, and industrial processes. Essentially, vacuum pressure measures how much the air has been reduced inside a container or system, helping us control environments and perform tasks that require minimal air or gas presence.
