What is Heat Conduction in Solids? - GCSE SCIENCE

WebThe heat transfer characteristics of solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It measures a substance’s ability to transfer heat through a material by conduction. Note that Fourier’s law applies to all matter, regardless of its state (solid, liquid, or gas). http://www.gcsescience.com/pen5-heat-conduction-vibration.htm

Web30 mrt. 2024 · Heat transfer via conduction in solid matter is more straight forward. In nonmetallic components, heat transfers via lattice vibrations (Phonon). The thermal conductivity transferred by phonons also exists in metals, but the more dominant form of conducted heat is via the high conductivity electrons. WebHeat can be transferred by conduction only in solids. If one end of a solid is heated, the particles of the solid gain kinetic energy. This means that they move faster. In a solid the particles are held together by strong forces of attraction. The only way in which the particles can move is to vibrate forwards and backwards.

WebThermal Conductivity is the amount of heat a particular substance can carry through it in unit time. Usually expressed in W/ (mK), the units represent how many Watts of heat can be conducted through a one meter thickness of said material with a one Kelvin temperature difference between the two ends. Web24 apr. 2024 · Surface. Heat conduction between materials depends partly on how their surfaces meet. If a surface is rough and uneven, contact and heat conduction are interrupted by gaps. Wood is full of microscopic gaps at its surface. Metals are smoother and have fewer gaps.
