title: "A glass window pane and a wooden wall panel have the same surface area and thickness, and both experience the same temperature difference between their inside and outside surfaces. The thermal conductivity of glass is greater than the thermal conductivity of wood. Which of the following correctly compares the rate of heat transfer by conduction through the glass pane, \\(H_{\\text{glass}}\\), to that through the wooden panel, \\(H_{\\text{wood}}\\), and provides the correct justification?"

# A glass window pane and a wooden wall panel have the same surface area and thickness, and both experience the same temperature difference between their inside and outside surfaces. The thermal conductivity of glass is greater than the thermal conductivity of wood. Which of the following correctly compares the rate of heat transfer by conduction through the glass pane, \(H_{\text{glass}}\), to that through the wooden panel, \(H_{\text{wood}}\), and provides the correct justification?

A glass window pane and a wooden wall panel have the same surface area and thickness, and both experience the same temperature difference between their inside and outside surfaces. The thermal conductivity of glass is greater than the thermal conductivity of wood. Which of the following correctly compares the rate of heat transfer by conduction through the glass pane, \(H_{\text{glass}}\), to that through the wooden panel, \(H_{\text{wood}}\), and provides the correct justification?

- **A.** \(H_{\text{glass}} > H_{\text{wood}}\), because the rate of heat transfer is directly proportional to thermal conductivity for a given thickness and temperature difference.
- **B.** \(H_{\text{glass}} < H_{\text{wood}}\), because a higher thermal conductivity indicates greater thermal resistance to energy flow through the material.
- **C.** \(H_{\text{glass}} = H_{\text{wood}}\), because the rate of heat transfer depends only on the geometric dimensions of the barrier and the temperature difference across it.
- **D.** \(H_{\text{glass}} > H_{\text{wood}}\), because glass has a higher specific heat capacity than wood, allowing it to transfer more energy per unit time.
