The thermal conductivity of silver is greater than the thermal conductivity of copper

The correct answer is option B: More. Silver has a higher thermal conductivity than copper. Thermal conductivity refers to a material’s ability to conduct heat. Silver, with a thermal conductivity of approximately 429 watts per meter Kelvin (W/mK), surpasses copper’s thermal conductivity of about 401 W/mK. This characteristic makes silver an excellent conductor of heat, often utilized in applications where efficient heat transfer is crucial, such as in electronics and thermal interface materials. Copper is also a good conductor but slightly less efficient than silver. Therefore, the correct answer is option B: more. Silver’s superior thermal conductivity makes it a preferred choice in various industries where heat management is essential for optimal performance and efficiency.
