What is the term for how readily a material conducts heat?

The term for how readily a material conducts heat is thermal conductivity. This property measures the ability of a material to transfer heat energy through it, which is crucial in various contexts, including firefighting. Understanding thermal conductivity helps firefighters assess materials' behavior in fire conditions, allowing them to make informed decisions regarding building construction, insulation, and protective gear. Higher thermal conductivity means a material can transfer heat more efficiently, which is vital for understanding how heat moves through structures during a fire scenario and how quickly it can affect firefighters and the materials surrounding them.

The other terms do not relate to heat conduction in this context. Thermal combustibility refers to a material's ability to catch fire and burn, which is not the same as how heat is conducted. Thermal connectivity is not a standard term used in discussing heat transfer and doesn't refer specifically to material properties. Thermal reducibility does not apply to heat conduction and typically relates to chemical reactions, particularly in the context of materials undergoing reduction.
