Answer

Brief Explanations:

Cohesion is the attraction between like - molecules, adhesion is the attraction between unlike - molecules, and surface tension is the elastic tendency of a fluid surface. A meniscus forms due to the balance between adhesion and cohesion. Water drops on a penny and spherical raindrops are due to surface tension. Dew drops on leaves and water strider walking on water are also related to surface tension. Wetting of a surface is adhesion. A paper towel absorbing water is adhesion as water molecules are attracted to the paper molecules.
