With the addition of impurities, surface tension of a liquid

Options

  1. Aincreases
  2. Bdecreases
  3. Cremains constant
  4. Dmay increase or decrease depending on impurities

Correct answer

D. may increase or decrease depending on impurities

Step-by-step solution

The addition of impurities in a liquid may increase or decrease the surface tension of liquid depending on the nature of impurities. If the impurities are highly soluble in liquid, then it will increase the surface tension. But if it is less soluble in liquid, then it will decrease the surface tension of liquid.
