When a liquid wets a solid, the adhesion forces between the liquid and the solid are greater than the cohesion forces between the liquid molecules. This causes the liquid to spread out on the surface of the solid.<\/p>\n<p>If the adhesion forces are less than the cohesion forces, the liquid will not wet the solid. Instead, the liquid will form droplets on the surface of the solid.<\/p>\n<p>The following are the explanations of each option:<\/p>\n<ul>\n<li>Option B: If the adhesion forces are more than the cohesion forces, the liquid will wet the solid very well. The liquid will spread out on the surface of the solid and form a thin film.<\/li>\n<li>Option C: If the adhesion forces are equal to the cohesion forces, the liquid will neither wet nor bead on the solid. The liquid will form a spherical droplet on the surface of the solid.<\/li>\n<li>Option D: The adhesion forces are not affected by temperature.
