What does K-Factor denote in heat transfer context?

• A. The amount of heat transferred
• B. Thermal conductivity
• C. Heat capacity
• D. Density

Answer: (A)

In this context, K-Factor is a proportionality constant that relates the driving conditions to the actual heat moved, so it represents the amount of heat transferred. When you see K used this way, it acts as the quantity produced by the transfer process under the given conditions, rather than a property of the material itself.

The other terms describe attributes of the material that influence how easily heat can flow or how much energy is needed to change temperature—thermal conductivity tells you how well the material conducts, heat capacity tells you how much energy is needed to raise its temperature, and density is mass per volume. These affect heat transfer rates and energy storage, but they are not the transfer quantity itself in this framework.
