Question: In a fluid flowing through a pipe, what effect does increasing the temperature have on its viscosity?

Options:

Correct Answer: Decreases viscosity

Solution:

Increasing the temperature generally decreases the viscosity of a fluid, making it flow more easily.

In a fluid flowing through a pipe, what effect does increasing the temperature have on its viscosity?

Step 1: Understand what viscosity is. Viscosity is a measure of how thick or sticky a fluid is.
Step 2: Recognize that temperature can affect how fluids behave.
Step 3: Learn that when you heat a fluid, its molecules move faster.
Step 4: Realize that faster-moving molecules can slide past each other more easily.
Step 5: Conclude that as the temperature increases, the viscosity of the fluid decreases.
Step 6: Understand that lower viscosity means the fluid can flow more easily.

Viscosity – Viscosity is a measure of a fluid's resistance to flow; it is affected by temperature.
Temperature Effect – Increasing temperature typically reduces the viscosity of liquids, allowing them to flow more freely.
