What is a consequence of having higher conductivity in metals?

Higher conductivity in metals means that they are more effective at transferring heat. Metals with high conductivity allow heat to flow through them quickly, which can result in an increase in temperature when exposed to a heat source. This characteristic is crucial in fire investigation, as understanding how heat moves through materials can help determine the origin and cause of a fire.

In industrial applications or during a fire scenario, metals that conduct heat well can pose risks such as rapid temperature rise and the potential for thermal expansion, which may affect other structural elements. Therefore, option C reflects the fundamental principle of thermal conductivity and its implications for temperature changes in conductive materials during exposure to heat.
