A) buoyancy B) specific heat C) surface tension D) capillary action

Answers

I think it's D) capillary action

Answer:The most appropriate answer would be D) capillary action.Capillary action refers to the movement of water through the spaces available in porous medium without the help of external forces.Forces like cohesion, adhesion, and surface tension help in the capillary action of the water.Capillary action takes place when the magnitude of adhesive forces (attraction of water molecules towards organic compound such as a capillary) is more than that of cohesive forces (attractive forces between the molecules of water). In plants, xylem act as capillaries through which water is pulled from the roots to the stem and other parts of the plant.In science class also the capillary action causes the uptake of blue water throughout the body of celery due to which it becomes blue in color.
