Meaning of conduction. It happens when the temperature of the molecules present in a substance increase, resulting in vigorous vibration. See more. In non-metals, the valence band is the highest range of electron energies in which electrons are normally present at absolute zero temperature, while the conduction band is the lowest range of vacant electronic states. Thermal conduction is the transfer of internal energy by microscopic collisions of particles and movement of electrons within a body. the transfer of thermal energy from one object to another because of a difference in temperature. “Convection” means the circulatory motion that occurs in a fluid of a nonuniform temperature owing to the variation of its a hot liquid or air that expands, becomes less dense, and rises or becomes more dense, and sinks. It takes place through either heat or electricity. answer choices . Conduction is when heat moves from one object to another object through direct touch. That was Conduction. In this section of Lesson 2, a third method of charging - charging by conduction - will be discussed. What is Thermal Conduction? Energy Glossary. The laws governing conduction of heat are very similar to Ohm’s Law, which governs electrical conduction. Definition of conduction in the Definitions.net dictionary. That was the power that had drawn me to the Underground, or drawn it to me. In solid-state physics, the valence band and conduction band are the bands closest to the Fermi level and thus determine the electrical conductivity of the solid. the transfer of heat through space. 2. The transfer of heat energy through a material (solid, liquid or gas) by the motion of adjacent atoms and molecules without gross displacement of the particles. Conduction occurs when energy is transferred from one atom or object to another. Definition of Electrical Conduction. Conduction heat transfer mainly occurs in solids or stationary mediums such as fluids at rest. Hence when an uncharged conductor is brought in contact with a charged conductor, charge is shared between the two conductors and hence the uncharged conductor gets charged. 1. 1. Heat conduction, also known as thermal conduction, is one of the three modes of heat transfer - the others are convection and radiation. | Meaning, pronunciation, translations and examples the transfer of heat by movements of a fluid. Definition of Conduction. To lead or guide: conducted the tourists through the museum. Conduction can occur in liquid, gaseous or solid objects. aberrant ventricular conduction the temporary abnormal intraventricular conduction of supraventricular impulses; called also ventricular aberration. 4. Conduction Defined in Simple Terms. Insulation is used to stop heat energy transfers from buildings and the human body. aberrant ventricular conduction the temporary abnormal intraventricular conduction of supraventricular impulses; called also ventricular aberration. Among the major elements in the cardiac conduction system are the sinus node, atrioventricular node, and the autonomic nervous system. Conduction is when heat or electricity moves from one place to another. Conduction (electricity) The passage of electric charges due to a force exerted on them by an electric field. 3. conduction definition: 1. the process by which heat or electricity goes through a substance: 2. the process by which heat…. Learn more. The transfer of sound waves, heat, nervous impulses or electricity. Conduction. Conduction is one of the ways that heat can transfer from one place to another. Electrical conduction is the transfer of electrically charged particles through a medium, such as electricity traveling through the power lines in your house. Information and translations of conduction in the most comprehensive dictionary definitions resource on the web. ... Electrical conduction through semiconductors is poorer than through metals, because fewer electrons are available as charge carriers. Another word for conduction. The rate of heat flow in a rod of material is Radiation. Conduction is described as the flow of heat from one solid to another, using a hot knife as an example. Conduction definition: Conduction is the process by which heat or electricity passes through or along something. Thermal conduction, also called heat conduction, occurs within a body or between two bodies in contactwithout the involvement of mass flow and mixing.It is the direct microscopic exchange of kinetic energy of particles through the boundary between two systems. Conduction, convection and radiation Energy can be transferred by conduction, convection and radiation. Convection definition, the transfer of heat by the circulation or movement of the heated parts of a liquid or gas. Definition of conduction noun in Oxford Advanced Learner's Dictionary. What is the definition of CONDUCTION? Conduction heat transfer is the transfer of heat by means of molecular excitement within a material without bulk motion of the mater. We use cookies to enhance your experience on our website, including to provide targeted advertising and track usage. conduction meaning: 1. the process by which heat or electricity goes through a substance: 2. the process by which heat…. conduction - the passing of heat from one object to another Thermal conduction, transfer of energy (heat) arising from temperature differences between adjacent parts of a body. Definition of Heat Conduction. In the previous two sections of Lesson 2, the process of charging by friction and charging by induction were described and explained. Conduction is the passage of energy, particularly electrical or heat, through matter. Conduction can be understood as the process, which enables direct transfer of heat through the matter, due to the difference in temperature, between adjacent parts of the object. Thermal energy flows spontaneously from bodies at higher temperatures to bodies at lower temperatures until the bodies are at equal temperature. The sinus node is a cluster of cells situated in the upper part of the wall of the right atrium. [n -S] Medical Definition of Conduction. The higher temperature object has molecules with more kinetic energy; collisions between molecules distributions this kinetic energy until an object has the same thermal energy throughout. What is Conduction? 1. Music To direct the performance of (an orchestra or chorus, for example). Energy Dictionaries. Thermal conductivity is attributed to the exchange of energy between adjacent molecules and electrons in the conducting medium. means the transmission of heat energy through material by way of the excitation of its molecules. Learn more. conduction [kon-duk´shun] conveyance of energy, as of heat, sound, or electricity. Sound conduction (or acoustic conduction) is the transfer of sound waves through a medium, such as vibrations from loud music passing through a wall. Charging by Conduction - definition Charging by conduction involves the contact of a charged object to a neutral object. For instance, one piece of metal could conduct heat from another piece of metal if the two are touching. Conduction Definition from Science & Technology Dictionaries & Glossaries. When heat is transferred from objects like rays of light or electromagnetically. If you've ever felt a shock while putting on a sweater, you have participated in electrical conduction. The little trick on the park bench was the power in miniature, for at its peak Conduction … The sinus node is the heart's natural pacemaker .
