SUMMARY
Viscosity varies significantly with temperature for both liquids and gases. For liquids, dynamic and kinematic viscosities are largely independent of pressure, with viscosity decreasing as temperature increases. In contrast, for gases, dynamic viscosity remains stable at low to moderate pressures, but kinematic viscosity is affected by pressure due to the gas density. As temperature rises, the viscosity of gases increases due to enhanced molecular collisions.
