Convection does not occur in solids because the particles within are too tightly packed to facilitate the process. Convection requires actual movement between the particles within a substance in order to transfer heat which is only possible in a fluid state of matter such as liquid or gas.Continue Reading
In convection, heat is transferred through the mass motion of a fluid. This movement creates heat currents that draw heat in specific directions and allow it to circulate throughout the systems. Liquid and gaseous substances have particles that are free flowing within the substance and allow the currents to travel through without disrupting the overall state of matter. Solids are composed of particles that are tightly packed and do not allow for much motion other than wiggling and collision.
Solid substances can transfer heat through conduction. Conduction is the process by which agitated particles in substance collide with nearby particles and pass on their energy. Liquids and gases can also transfer heat through conduction, but they are less efficient at the process because it requires direct contact and collision between particles. The thermal conductivity is related to electrical conductivity and both can vary greatly depending on the chemical compounds or elements, although generally speaking the best conductors of both are metallic compounds.Learn more about States of Matter
Examples of solids in gas solutions include hydrogen in platinum and sulfur vapor in air. In chemistry and physics, there are three states of matter, which are solid, liquid and gas. From these states seven different types of solutions can form, including gas solutions, which involve the dissolving of gas particles into surrounding solid substances or the dissolving of solid particles into gas.Full Answer >
Amorphous solids are solids which do not have an crystalline structure. There is no particular order to the make up of these types of solids. When viewed under a microscope or when x-rayed, the molecules that make up the solid are never in the same order from one piece to another.Full Answer >
Filtration is the method through which solids are taken out of a liquid or gas combination. Examples of filtration include coffee filters to split up the coffee from the grounds, belt filters for extraction of precious metals, HEPA filters for air conditioning, pneumatic conveying systems, sparkler filters and Buchner funnels.Full Answer >
The element mercury is the most dense liquid and is even more dense than many solids. It has a density of 13.5336 grams per cubic centimeter. Mercury is the only pure metal element that is a liquid at room temperature.Full Answer >
