To dissolve is to cause a solute to pass into a solution. This involves a solid going into a liquid. Dissolving is also called dissolution. When alloys form, one solid dissolves into another solid.
Sugar dissolves in water. Oil does not dissolve in water. Salt dissolves in water to form a solution. The ability to dissolve depends on the substance and solvent. Solubility depends on temperature, pressure, and chemical properties.
Factors Affecting Dissolution
What are three examples of dissolving? Examples of dissolution include sodium chloride dissolving in water, water dissolving in 2-propanol to form rubbing alcohol, and zinc dissolving in copper to form brass. Several factors affect the rate of dissolution. These include polarity, temperature, pressure, and surface area of the solute.
Dissolving Process
Dissolving differs from fading. A dissolve transition happens at once on screen. Fading has a black screen in between.
What are some examples of substances that dissolve easily? There are many substances that dissolve easily in water or other solvents. Some examples of substances that dissolve easily include: Sugar. Salt. Typically, this involves a solid going into a liquid phase, but dissolution can involve other transformations as well.
Dissolving happens when the attraction between the particles of the solvent and solute are strong enough to overcome the attraction of the particles of the solute for one another. As each solute molecule gradually breaks away, water molecules surround it, and it drifts into solution. If the solute is a solid, this process happens gradually.
In summary, not all substances can be dissolved, and the ability of a substance to dissolve in a solvent depends on the nature of the substance and the solvent. Solubility is the maximum concentration of a solute that can dissolve in a solvent at a given temperature.
Dissolving in Filmmaking
A dissolve is a gradual transition from one image to another. Dissolves typically happen over 24-48 frames. George Melies first used dissolves in 1899 in Cinderella. This was the first motion picture with scenes pieced together.
Before digital editing, optical printers created dissolves. Live-action, animation, and models combined into one shot. Adobe Premiere Pro now makes dissolves easier.
In Spaceballs, Mel Brooks uses a clean dissolve. It shows the character’s feelings without cuts or exposition. The dissolve overlaps two shots, transitioning from one scene to the next. It can show time passing or change of location.
Dissolves became more than editing transitions. They took on new meanings in visual literacy. In Spellbound, two dissolves have different meanings. One shows entering a dream state. The other is in a montage sequence.
The dissolve is a powerful filmmaking tool. It allows seamless scene transitions with fluidity and continuity. A graduation fade to black or quick cut to the next shot enhances storytelling. For example, signify time passing as one scene slowly blends into another. Or juxtapose contrasting images like a happy couple years later sitting in silence.
