WitrynaA jet of liquid is unstable because of surface tension and usually breaks into small droplets. The addition of minute quantities of polymeric molecules provides an additive elastic stress which stabilizes the liquid column. In this situation the terminal droplet has the time to gobble many of its incoming neighbors before its detachment. Witryna9 gru 2024 · The surface tension is also related to the vapor pressure and the latent heat, which are as well-defined for a solid as they are for a liquid. The surface tension of the solid-vapor interface is the sum of those for the solid-liquid and liquid-vapor interfaces, just as the latent heat of sublimation is the sum of the latent heats for … florida department of economic servicesWitrynaThe answer is the option (c) Tension & surface tension.
