A plane wall of thickness $0.1\text{ m}$ and thermal conductivity $50\text{ W/m}\cdot\text{K}$ has a surface area of $2\text{ m}^2$. The temperature difference across the wall is $100\text{ K}$. What is the rate of heat transfer through the wall?
Show Hint
Be careful with units when performing calculations.
Ensure the final answer is converted from watts ($\text{W}$) to kilowatts ($\text{kW}$) by dividing by 1,000 as required by the options.
