What is the SI unit of thermal conductivity?
Correct Answer: Watts per meter per Kelvin (W/m·K)
- Step 1: Understand that thermal conductivity measures how well a material conducts heat.
- Step 2: Know that the SI unit system is a standard way to measure scientific quantities.
- Step 3: Identify the components of the unit for thermal conductivity: Watts (W) for power, meters (m) for distance, and Kelvin (K) for temperature.
- Step 4: Combine these components to form the unit: Watts per meter per Kelvin (W/m·K).
- Step 5: Conclude that the SI unit of thermal conductivity is W/m·K.
