Question: In which of the following scenarios would you expect to observe a decrease in viscosity?

Options:

Correct Answer: Heating a liquid

Solution:

Heating a liquid generally decreases its viscosity, allowing it to flow more freely.

In which of the following scenarios would you expect to observe a decrease in viscosity?

In which of the following scenarios would you expect to observe a decrease in viscosity?

Step 1: Understand what viscosity means. Viscosity is a measure of how thick or sticky a liquid is.
Step 2: Know that heating a liquid usually makes it less thick. This means it can flow more easily.
Step 3: Think of examples: When you heat honey, it becomes runnier. This shows a decrease in viscosity.
Step 4: Remember that when a liquid is heated, its molecules move faster and can slide past each other more easily.
Step 5: Conclude that in scenarios where a liquid is heated, you would expect to see a decrease in viscosity.

Viscosity – Viscosity is a measure of a fluid's resistance to flow; it decreases with increased temperature.
Effect of Temperature on Viscosity – Heating a liquid typically reduces its viscosity, making it less resistant to flow.
