nullrõhk
Nullrõhk refers to a state where the pressure within a system is lower than the ambient atmospheric pressure. This concept is often encountered in engineering and physics. For instance, in vacuum systems, the goal is to achieve and maintain a nullrõhk to facilitate specific processes. This low-pressure environment can prevent unwanted chemical reactions, allow for the outgassing of materials, or be essential for the operation of certain scientific instruments.
Achieving nullrõhk typically involves the use of pumps that remove gas molecules from a contained space. The
