temperature effect on viscosity

Temperature has a significant impact on viscosity, which is a fluid’s resistance to flow. As temperature increases, particles in the fluid gain energy and move more rapidly, reducing the internal friction and making the fluid less viscous. Conversely, lowering the temperature causes particles to move slower, increasing friction and making the fluid thicker and more resistant to flow. In other words, warmer fluids tend to flow more easily, while colder fluids are thicker and flow less readily. This relationship is important in many applications, from engine oils to medical fluids, where controlling flow properties is essential.
