Mercury has a very high surface tension. Would capillary action occur if you insert a thin tube into a pool of mercury? Assume the cohesive forces in mercury are greater than the adhesive forces with the tube.A) Yes, capillary action will draw the mercury up into the tube.B) No, capillary action only occurs if cohesive forces are less than adhesive forces.C) Yes, capillary action will draw the mercury up the outside of the tube.D) Yes, capillary action will pull the mercury down in the tube.

The correct answer is B) No, capillary action only occurs if cohesive forces are less than adhesive forces. Capillary action is a result of the interplay between cohesive forces and adhesive forces.

Cohesive forces are the attractive forces between molecules of the same substance, while adhesive forces are the attractive forces between molecules of different substances. For capillary action to occur, the adhesive forces between the tube and the liquid must be greater than the cohesive forces within the liquid. However, in the case of mercury, the cohesive forces are much greater than the adhesive forces, so capillary action would not occur. Therefore, inserting a thin tube into a pool of mercury would not cause the mercury to be drawn up into the tube.
