It seems like your question got cut off. If you're asking about how often pressure changes occur in a specific context, such as in weather systems or in a mechanical environment, please provide more details. In general, pressure fluctuations can happen frequently, depending on the system or environment, ranging from daily changes in atmospheric pressure to more gradual shifts in industrial processes. If you clarify your question, I can provide a more tailored answer!
Barometric pressure is often abbreviated as "BP" in meteorology and scientific contexts.
As often as it wants. It all depends on how much pressure is building up underneath it.
A falling pressure typically indicates that the weather is changing from high pressure to low pressure. This can often be associated with approaching storm systems and potentially unsettled weather conditions.
Millibars are a unit of pressure often used in weather forecasting. Atmospheric pressure is commonly measured in millibars, with typical values ranging from around 980 to 1050 millibars. High pressure systems are associated with fair weather, while low pressure systems are often associated with clouds, rain, or storms.
low air pressure because it said in the book general science that almost all stors are caused by low air pressure.
A pressure gradient is the change in pressure over a specific distance. It is often used to describe how pressure changes in the atmosphere or in a fluid system. Pressure gradients often drive the flow of fluids from high pressure areas to low pressure areas.
PSI (Pressure per Square inch)
Rain most often occurs with low pressure.

You should generally sail with high pressure, as low pressure often brings storms.
High pressure means nice weather, so Southern Europe often has nice weather.

High blood pressure can often be symptomless. Often times, drug stores have machines that provide free blood pressure testing. Try one of those or schedule a doctor visit to know whether you have high blood pressure for sure.

Hot water does exert pressure, but the main thing is that it creates steam if hot enough, and that is often used to run machines that require pressure.
