undefined video tutorial00:01:48
A soap bubble of radius 12 cm is blown. Surface tension of soap solution is 30 dyne/cm. Calculate the work done in blowing the soap bubble.
Draw a neat labelled diagram of rise of liquid in capillary tube showing different components of tension (force).
If two capillary tubes of different diameters are partially dipped in the same liquid vertically, then the rise of liquid ..........
a) is same in both the tubes
b) is more in the tube of larger ~iameter
c) will not be in smaller diameter tube
d) is more in the tube of smaller diameter
