Question

Mark the statement which is correct:
(a) surface tension of a liquid increases with temperature
(b) addition of chemicals reduces the surface tension of a
liquid
(c) stalagmometer is used for measuring viscosity of the
liquid
(d) viscosity of the liquid does not depend on
intermolecular forces​

Answer 1

Answer:

option b

Explanation:

option a is wrong cause surface tension decreases on increasing temperature due to higher energy of molecules and weaker attractive forces

option c is wrong cause stalagmometer is used to measure surface tension, not viscosity

option d is also wrong cause viscosity depends on intermolecular force.

Therefore the right option is b

Hope this helps.
