Which of the following factors does NOT affect the surface tension of a liquid?

Which of the following factors does NOT affect the surface tension of a liquid?

Correct Answer: Density

Step 1: Understand what surface tension is. It is the property of a liquid that makes its surface behave like a stretched elastic membrane.
Step 2: Identify the factors that can affect surface tension. These include temperature, impurities (like soap or salt), and the nature of the liquid (like water vs. oil).
Step 3: Recognize that temperature affects surface tension because heating a liquid usually decreases its surface tension.
Step 4: Know that impurities can change the surface tension by either increasing or decreasing it, depending on the substance.
Step 5: Understand that the nature of the liquid itself determines its inherent surface tension characteristics.
Step 6: Now, consider density. While density is a property of a liquid, it does not directly change the surface tension.
Step 7: Conclude that among the options given, density is the factor that does NOT affect surface tension.
