Q. The phenomenon of capillary action is primarily due to:
A.
Surface tension and cohesion
B.
Surface tension and adhesion
C.
Viscosity and density
D.
Gravity and pressure
Solution
Capillary action occurs due to the combination of surface tension (which pulls the liquid up) and adhesion (which attracts the liquid to the walls of the tube).
Q. The shape of a soap bubble is spherical because:
A.
It minimizes volume
B.
It maximizes surface area
C.
It minimizes surface area for a given volume
D.
It is the only stable shape
Solution
A soap bubble adopts a spherical shape because it minimizes the surface area for a given volume, which is energetically favorable due to surface tension.
Correct Answer:
C
— It minimizes surface area for a given volume
