In an experiment surface tension of water at 200C is found 7.26 × 10–2 N/m. If he does the experiment at a temperature 300C, then the surface tension of water will be –
A
(a) More than 7.26 × 10–2 N/m
A
(b) Less than 7.26 × 10–2 N/m
A
(c) Equal to 7.26 × 10–2 N/m
A
(d) Can't say anything
Explanation
Solution
(b)
As temperature increases, surface tension decreases.
