Capillarity and Capillary Action

A liquid rises in glass capillary tube upto a height of 2.5 cm at room temperature. If another glass capillary tube having radius half that of the earlier tube is immersed in the same Liquid, the rise of liquid in it will be _______.

Calculate the density of paraffin oil, if glass capillary of diameter 0.25 mm dipped in paraffin oil of surface tension 0.0245 N/m rises to a height of 4 cm. (Angle of contact of paraffin with glass = 28^° and acceleration due to gravity = 9.8 m/s².)

Two soap bubbles have radii in the ratio 4:3. What is the ratio of work done to blow these bubbles?

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 for a liquid surface in contact with a solid, when the angle of contact is acute.

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

Explain the rise of liquid in the capillary on the basis of pressure difference.
