A glass window 0.53 cm thick measures 86 cm by 39 cm.
How much heat flows through this window per minute if the inside and outside temperatures differ by 17 C∘?
Express your answer using two significant figures.
Rate of heat flow through window,
dQ/dt = k A dT/d
dQ/dt = 0.84 x (0.86 x 0.39) x 17/(0.53 x 10^-2)
dQ/dt = 903.68 J/s = 54.22 kJ/min

A glass window 0.35 cm thick measures 61 cm by 36 cm. How much heat flows through this window per minute if the inside and outside temperatures differ by 17° C? in kJ/min
A glass window is 0.53cm thick measures 81cm by 38cm. How much heat flows through this window per minute if the inside and outside temperatures differ by 17 degrees C?
A glass window 0.35 cm thick measures 85 cm by 35 cm . If the inside and outside temperatures differ by 17 ∘, the heat flows through this window per minute is 73 kJ . Part A To compare the relative efficiency of air and glass as insulators, calculate the heat flows through this window per minute with a 0.35 cm thick layer of air instead of glass. Part B By what factor is the rate of heat transfer reduced?
A Thermopane window consists of two glass panes, each 0.50 cm thick, with a 1.0 cm thick sealed layer of air between. If the inside temperature is 22.0°C and the outside temperature is 0.0°C, determine the rate of heat transfer through 1.0 m2 of the window. Compare this with the rate of heat transfer through 1.0 m2 of a single 1.0 cm thick pane of glass.
A Thermopane window consists of two glass panes, each 0.50 cm thick, with a 1.0 cm thick sealed layer of air between. If the inside temperature is 23.5°C and the outside temperature is 0.0°C, determine the rate of heat transfer through 2.0 m2 of the window. Compare this with the rate of heat transfer through 2.0 m2 of a single 1.0 cm thick pane of glass. J/s (Thermopane window) J/s (Single pane window)

A window glass has dimensions, 1.04 m high, 2.34 m wide and 1.341 cm thick, with a thermal conductivity of 0.81 Wm10c-1. The outside- surface temperature is 32 °C and the inside-surface temperature is 24°c. Calculate the rate of heat transfer, in watts, through a plane of window glass, giving your answer to 3 decimal places.
