A cloudburst is an extreme form of production of liquid water from a supersaturated mixture of air and water vapour in the atmosphere. Supersaturation in the vapour phase is related to the surface tension of liquids through the Kelvin equation, the Gibbs–Thomson effect and the Poynting effect. [9]
Dispersion is a process by which (in the case of solid dispersing in a liquid) agglomerated particles are separated from each other, and a new interface between the inner surface of the liquid dispersion medium and the surface of the dispersed particles is generated. This process is facilitated by molecular diffusion and convection. [4]
While a Mentos candy contains millions of cavities, it is likely that only about 100,000 cavities actively nucleate bubbles on any single Mentos candy placed in a carbonated beverage. [ 20 ] [ 26 ] Pre-existing bubbles provide a way for the reaction to occur without requiring bubbles to form within the liquid itself (homogeneous nucleation).
The term phase is sometimes used as a synonym for state of matter, but it is possible for a single compound to form different phases that are in the same state of matter. For example, ice is the solid state of water, but there are multiple phases of ice with different crystal structures , which are formed at different pressures and temperatures.
As described by a 1980 patent, the candy is made by dissolving sugars in water and is evaporated at 320 °F (160 °C) until the water content is 3% by mass. [10] The water and sugar mixture is then cooled to 280 °F (138 °C), and while being intensely stirred, it is pressurized with carbon dioxide at 730 pounds per square inch [psi] (50 atm). [10]
is the steady state radius; is the steady state pressure; is the mass density of the surrounding liquid; For air bubbles in water, smaller bubbles undergo isothermal pulsations. The corresponding equation for small bubbles of surface tension σ (and negligible liquid viscosity) is [8]
In chemistry, a suspension is a heterogeneous mixture of a fluid that contains solid particles sufficiently large for sedimentation. The particles may be visible to the naked eye , usually must be larger than one micrometer , and will eventually settle , although the mixture is only classified as a suspension when and while the particles have ...
Helimagnetism: A state with spatially rotating magnetic order. Spin glass: A magnetic state characterized by randomness. Quantum spin liquid: A disordered state in a system of interacting quantum spins which preserves its disorder to very low temperatures, unlike other disordered states.
