Contact angle between water and glass
WebDue to the surface tension, the surface of the liquid acts as a stretched membrane. So even if some more water than the rim level of the glass is poured into it, the stretched water surface which holds the glass rim due to adhesion becomes convex upward and the contact angle between the water and the glass becomes more than 90° in this situation. WebThe heterogeneous situation corresponds to two nucleation locations, namely, the solid–liquid interface and the air–liquid interface with the contact angles of θ and φ, respectively. b ...

The contact angle depends upon the medium above the free surface of the liquid, and the nature of the liquid and solid in contact. It is independent of the inclination of solid to the liquid surface. It changes with surface tension and hence with the temperature and purity of the liquid. See more The contact angle is the angle, conventionally measured through the liquid, where a liquid–vapor interface meets a solid surface. It quantifies the wettability of a solid surface by a liquid via the Young equation. A given … See more On the basis of interfacial energies, the profile of a surface droplet or a liquid bridge between two surfaces can be described by the See more Control of the wetting contact angle can often be achieved through the deposition or incorporation of various organic and inorganic molecules onto the surface. This is often achieved … See more • Goniometer • Meniscus (liquid) • Porosimetry See more The shape of a liquid–vapor interface is determined by the Young–Dupré equation, with the contact angle playing the role of a boundary condition via the Young equation.
