Which of the following statements is incorrect?
1. The property of liquid drops to have minimum surface area is called surface tension.
2. Surface tension of liquids decreases with rise in temperature.
3. The SI unit of surface tension in \(\mathrm{Nm}^{-1}\).
4. Magnitude of surface tension is less, when there is strong attractive force between the molecules.
1
2
3
4
Solution
Statements 1, 2 and 3 are correct, but statement 4 is incorrect, because stronger intermolecular attractive force between molecules will give higher magnitude of surface tension.
