Answer 2

Answer:

The correct option is 4. Material of the plate.

Explanation:

• Thermal conductivity's coefficient is an inherent quality. Instead of the dimensions, it depends on the material.
• The letter "k" stands for the thermal conductivity coefficient. Since this is a physical characteristic of the substance, the temperature has no bearing on it.
• It won't change whether the material is long or short, thick or thin, therefore neither its thickness nor its length will have any bearing on it.
• The type of material, not its temperature, shape, or size, determines the coefficient of heat conductivity.
