Description : Why does a small quantity of liquid assume spherical form?
Last Answer : Ans: A small quantity of liquid assumes a spherical form due to surface tension which tends to reduce the surface area. A given mass will acquire minimum surface area if it assumes a spherical shape.
Description : A falling drop of rain water ac-quires the spherical shape due to – (1) Viscosity (2) Surface Tension (3) Atmospheric pressure (4) Gravitational force
Last Answer : (2) Surface Tension Explanation: Raindrops start out as round high in the atmosphere as water collects on dust and smoke particles in clouds. But as raindrops fall, they lose their rounded ... the molecules stick together. The cause is the weak hydrogen bonds that occur between water molecules.

Description : Rain drops acquire spherical shape due to - (1) viscosity (2) surface tension (3) friction (4) elasticity
Last Answer : (2) surface tension Explanation: The Surface tension pulls the surface of the drop equally at all points thus produces the spherical shape having the minimum surface area.
Description : A solid ball of metal has a spherical cavity inside it. When the ball is heated the volume of the cavity will - (1) Increase (2) decrease (3) remain unaffected (4) have its shape changed
Last Answer : (1) Increase Explanation: The metal ball can be considered to be made up of several layers of thinner ones. On heating each of these layers will increase in radius. As the inner most layer also increases its radius, the volume inside it i.e, the volume of the hollow portion will also increase.
