How does temperature affect fuel viscosity?

• A. Increased temperature increases viscosity
• B. Increased temperature decreases viscosity
• C. Temperature has no effect on viscosity
• D. Decreased temperature decreases viscosity

Answer: (B)

Temperature has a significant impact on the viscosity of fuel. As temperature increases, the kinetic energy of the fuel molecules also rises, causing them to move more freely and with less resistance. This results in a decrease in viscosity, allowing the fuel to flow more easily. In lower temperatures, fuel molecules are less energetic and move more slowly, which can make the substance more viscous and thicker. Understanding this relationship is crucial for maintaining effective fuel delivery systems, as changes in viscosity directly affect the performance and efficiency of engines and other equipment relying on fuel. Thus, a higher temperature leads to lower viscosity, enhancing flow characteristics and system performance.
