← ScienceWhich outcome occurs when a viscous hydraulic fluid heats?
A)Increased internal leakage within system✓
B)Decreased resistance to turbulent flow
C)Improved seal performance at joints
D)Enhanced lubrication between moving parts
💡 Explanation
Increased temperature in a viscous fluid causes a reduction in its viscosity. This lowers the fluid's resistance to flow through gaps and seals, initiating increased internal leakage, because of decreased intermolecular forces; therefore leakage increases, rather than pressure or other lubrication improvements.
