How does the surface tension of a liquid vary with increase in temperature?
A
Remains same
B
Decrease
C
Increases
D
No regular pattern is followed.

Decrease
Explanation
Solution
: Increase in temperature increase the kinetic energy of the molecules and effectiveness of intermolecular attraction decrease, so surface tension decreases as the temperature is raised.
