The heat loss h (in watts) through a single-pane glass window varies jointly with the window's area A (in square meters) and the difference between the inside and outside temperatures d (in kelvins). Write an equation relating h, A, d, and a constant k. If a single-pane of glass with an area of 1.00 square meter and a temperature difference of 1.00 kelvin has a heat loss of 5.70 watts, then what is the heat loss through a single-pane window with an area of 2.50 square meters and a temperature difference of 20 kelvins?
