Why do solids conduct better heat than liquids and gases? Describe waves and particles. What types of atoms typically form ionic bonds? Can atoms disappear? Why do objects float in liquids denser than themselves? Explain the elastic properties of a matter on the basis of interatomic forces. ...
In airy melamine foam, only a very limited amount of casing stays in place, and the strands that do are located where the edges of several air pockets overlapped. The foam is flexible because each tiny strand is so slender and small that bending the entire eraser is easy. The ...
All preparedfooddishes are examples of a mixture known as a colloid. A colloid is a material composed of tiny particles of one substance that are dispersed, but not dissolved, in another substance. The mixture of the two substances is a colloidal dispersion or a colloidal system. The coll...
The particles could be too small, or moving too fast, to be seen, or perhaps our eyes see right through them. As it turns out, all of these theories are both right and wrong at once. And they're all useful in describing certain behaviors of light....
This is because the molecules in the water move farther apart as the temperature increases, allowing more of the powder to be dissolved. As the solution cools down, there is all of a sudden going to be more particles in the water as the molecules move back together. ...
Crystal growing is a neat chemistry project that is a quick set up involving liquids, solids, and soluble solutions. Because there are still solid particles within the liquid mixture, if left untouched, the particles will settle to form crystals. ...
Oobleck is a non-Newtonian fluid, meaning its viscosity changes under stress or force. When you apply pressure, like squeezing or tapping it, the cornstarch particles lock together, and the mixture behaves like a solid. When the pressure is released, it flows like a liquid. This unique prope...
Depending on the degree of abrasion the surface is exposed to, i.e., currents and particles, parts of the surface can be abraded away. The magnesium rich phases are typically observed in cracks and cavities rather than on the surface when exposed to an abrasive environment, which could ...
Filtration: The water is sent through filters or membranes whose holes will only let through extremely small particles, typically those smaller than 1 micron. Contaminants larger than 1 micron, including many germs and inorganic solids, can't make it through. Distillation: The water is vaporized....
Why does CAMSIZER 3D represent a step forward in particle analysis and the characterization of bulk solids? Our world is three-dimensional. Thus, 2D images are unable to fully represent or even describe 3D objects and only exist in theory, such as on a piece of paper or a computer screen....
