Canvas - Water Droplets

from $40.00
A water droplet is a small mass of liquid water, typically held together by surface tension . This surface tension is a direct result of the strong cohesive forces (hydrogen bonds) that cause water molecules to be highly attracted to each other, creating an inward pull on the molecules at the surface and minimizing the overall surface area, hence, the tendency for small droplets to form a near-perfect spherical shape. Droplets are fundamental to the water cycle, forming when water vapor in the atmosphere cools and undergoes condensation, often collecting around tiny particles like dust or pollution, known as "cloud condensation nuclei." Once these droplets grow heavy enough, gravity pulls them down as precipitation, such as rain. The way a droplet interacts with a surface is determined by the balance between these cohesive forces and adhesive forces (attraction to the surface material): strong adhesion means the droplet spreads out (wetting), while stronger cohesion causes it to bead up on hydrophobic (water-repelling) surfaces.
