lämpöjohdot
Lämpöjohdot, known in English as thermal conductivity, is a fundamental physical property of a material that describes its ability to conduct heat. It quantifies how effectively thermal energy is transferred through a substance when there is a temperature difference. Materials with high lämpöjohdot, such as metals like copper and aluminum, are excellent heat conductors. This means that heat can pass through them quickly and efficiently. Conversely, materials with low lämpöjohdot, such as wood, plastic, and air, are good thermal insulators. They resist the flow of heat, slowing down its transfer.
The value of lämpöjohdot is typically measured in watts per meter-kelvin (W/(m·K)). A higher value indicates a
