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.Know More
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
The five states of matter include Bose-Einstein condensates, solids, liquids, plasmas and gases. Matter is anything that occupies space and has weight. Matter may change its state when energy is increased or decreased.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 >
By definition, solids have a fixed volume. The atoms or molecules composing a solid are closely packed together and are stabilized by interatomic or intermolecular forces, making them resistant to further compression.Full Answer >
Most metals are solids at room temperature as they have high melting points. Mercury is the only metal that occurs in liquid form at this temperature.Full Answer >
