The nonpolar molecules of mercury do not interact strongly with the polar molecules of glass, so they do not form a strong bond.<\/p>\n<p>Cohesion is the force that holds together the molecules of a single substance. In the case of mercury, the cohesive forces are very strong. This is because mercury is a very dense liquid, and its molecules are attracted to each other strongly. The strong cohesive forces in mercury cause it to form drops, rather than spreading out on a surface.<\/p>\n<p>Surface tension is the tendency of a liquid surface to contract into the smallest possible area. This is due to the cohesive forces between the molecules of the liquid. In the case of mercury, the surface tension is very high. This is because mercury is a very dense liquid, and its molecules are attracted to each other very strongly. The high surface tension of mercury causes it to form drops that are very spherical.<\/p>\n<p>Viscosity is a measure of how easily a liquid flows. In the case of mercury, the viscosity is very high. This is because mercury is a very dense liquid, and its molecules are attracted to each other very strongly. The high viscosity of mercury makes it difficult to pour or spread.<\/p>\n<p>In conclusion, the correct answer is A. adhesion.
