In the conductive heat loss equation Q = A × ΔT / RSI, what does Q represent?

Explanation:
Q is the rate at which heat is transferred through the surface, the heat flow per unit time, measured in watts. In the formula, area times the temperature difference (A × ΔT) represents the driving potential for heat flow, and dividing by RSI (thermal resistance) shows how insulation slows that flow. The units line up as m² × °C divided by m²°C/W, giving watts. So increasing surface area or temperature difference raises Q, while a higher RSI (more insulation) lowers Q.
