Thermal conduction - Wikipedia
网页Thermal conduction is the diffusion of thermal energy (heat) within one material or between materials in contact. The higher temperature object has molecules with more kinetic energy; collisions between molecules distributes this kinetic energy until an object has the same kinetic energy throughout.
Heat Transfer – Conduction, Convection, Radiation - Science …
网页2022年9月18日 · The three types of heat transfer are conduction, convection, and radiation. Heat transfer occurs when thermal energy moves from one place to another. Atoms and molecules inherently have kinetic and thermal energy, so all matter participates in heat transfer.
热传导 - 百度百科
网页热传导（thermal conduction）是介质内无宏观运动时的传热现象，其在固体、液体和气体中均可发生，但严格而言，只有在固体中才是纯粹的热传导，而流体即使处于静止状态，其中也会由于温度梯度所造成的密度差而产生自然对流，因此，在流体中热对流与热传导 ...
Thermal conductivity and resistivity - Wikipedia
网页Thermal conduction is defined as the transport of energy due to random molecular motion across a temperature gradient. It is distinguished from energy transport by convection and molecular work in that it does not involve macroscopic flows or work-performing internal stresses.
Thermal conduction | Heat Transfer, Temperature, Conduction
网页2024年9月4日 · thermal conduction, transfer of energy (heat) arising from temperature differences between adjacent parts of a body. Thermal conductivity is attributed to the exchange of energy between adjacent molecules and …
14.5: Conduction - Physics LibreTexts
网页2022年2月20日 · Some materials conduct thermal energy faster than others. In general, good conductors of electricity (metals like copper, aluminum, gold, and silver) are also good heat conductors, whereas insulators of electricity (wood, …
Thermal conductivity | Definition, Science, & Applications
网页Thermal conductivity, the ability of a substance to conduct heat or move heat from one location to another without the movement of the material conducting the heat. Thermal conductivity is measured in watts per meter kelvin (W/mK). For example, solid aluminum has a thermal conductivity of 237 W/mK.
Heat transfer | Definition & Facts | Britannica
网页2024年8月29日 · heat transfer, any or all of several kinds of phenomena, considered as mechanisms, that convey energy and entropy from one location to another. The specific mechanisms are usually referred to as convection, thermal radiation, and conduction (see thermal conduction). Conduction involves transfer of energy and entropy between adjacent molecules ...
网页Heat transfer processes are classified into three types. The first is conduction, which is defined as transfer of heat occurring through intervening matter without bulk motion of the matter.
