Sutherland's Law

Sutherland's Law describes how the viscosity, or thickness, of a gas decreases as temperature increases. Specifically, it states that the viscosity of a gas is proportional to the temperature raised to the 1.5 power (or 3/2). This means that when a gas gets hotter, its molecules move faster and slide past each other more easily, making the gas less viscous. This principle is important in fields like aerodynamics and engineering, helping predict how gases behave under different temperature conditions, such as in high-speed aircraft or atmospheric studies.
