The surface tension does not depend upon:

Question

The surface tension does not depend upon: (A) Presence of impurities (B) Temperature (C) Atmospheric pressure (D) Nature of the liquid

Tardigrade Admin · Accepted Answer

Due to the presence of impurities cohesive force decreases because attraction among the particle of liquid or substance decreases due to which surface tension decreases. Surface tension depends on temperature also as St=So(1-α Δ T)

Q. The surface tension does not depend upon:

Presence of impurities

Temperature

Atmospheric pressure

Nature of the liquid

Due to the presence of impurities cohesive force decreases because attraction among the particle of liquid or substance decreases due to which surface tension decreases. Surface tension depends on temperature also as $S_{t} = S_{o} (1 - α Δ T)$
