If the surface area of anu liquid surface is increased by 50 % then its surface tension will

A

increase by 50%

B

decrease

C

not change

D

be doubled

Text Solution

Verified by Experts

The correct Answer is:
C
`T = (dW)/(dA)`
To increase the area , we have to do additional work .
But S.T = Work done per unit area does not change
