Dynamic viscosity of gas from temperature¶
Viscosity is a phenomenon of molecular transport, the property of fluid bodies (liquids and gases) to resist the movement of one part of them relative to another. As a result, the macroscopic work expended on this movement is dissipated as heat. Unlike liquids, the viscosity of gases increases with increasing temperature, whereas for liquids it decreases with increasing temperature.
Conditions:
The gas is ideal.
