Gas will not flow from a point of lower pressure to which condition?

Gas naturally flows from areas of higher pressure to areas of lower pressure due to the principles of fluid dynamics. In this context, when gas is at a point of lower pressure, it will not flow towards a higher pressure area.

The mechanics of gas flow rely on the pressure gradient; therefore, a significant difference in pressure is necessary for movement. Understanding this principle is crucial in applications related to gas distribution and safety, as it ensures that in systems designed for gas transport, the gas will always move in a predictable direction, helping to prevent leaks and other issues.

The options related to equal pressure or vacuum illustrate conditions where flow dynamics differ but do not violate the fundamental behavior of gases under pressure. Gas will either remain static in equal pressure or move towards a vacuum if conditions allow, but it will never flow against the natural gradient towards higher pressure.
