1.
heat conduction; thermal conduction
The transfer of thermal energy through a material by direct contact between particles, without the material itself moving. A physics and engineering term that also appears in discussions of cookware and building materials.
銅は熱伝導が良い。
Copper has good heat conduction.
このフライパンは熱伝導が高く、素早く温まる。
This frying pan has high thermal conductivity and heats up quickly.
金属と木では熱伝導の速さが大きく異なる。
The speed of heat conduction differs greatly between metal and wood.
A scientific term combining 熱 (heat) and 伝導 (conduction, transmission). Used in physics and engineering, as well as in consumer contexts describing cookware, thermal insulation, and electronics cooling.
COMMON COLLOCATIONS:
- 熱伝導が良い / 悪い: has good / poor heat conduction
- 熱伝導率: thermal conductivity (coefficient)
- 熱伝導性: thermal conductivity (property)
- 熱伝導シート: thermal conduction sheet (used in electronics)
RELATED TERMS:
- 対流: convection — heat transfer via fluid movement
- 放射: radiation — heat transfer via electromagnetic waves
- 断熱: heat insulation — blocking heat transfer
