One of the glass windows (k = 0.80 W/m $\circ$ C)in your house has an area of 1.21 m² and a thickness of 5 mm.When the temperature difference between its surfaces is 25 $\circ$ C,the rate of energy transferred through the window is

Question

Quizplus · Accepted Answer

We can use the formula for the rate of energy transfer through a window:

Q/t = kA (ΔT/d)

where Q/t is the rate of energy transfer, k is the thermal conductivity, A is the area of the window, ΔT is the temperature difference, and d is the thickness of the window.

Plugging in the given values, we get:

Q/t = (0.80 W/m°C)(1.21 m²)(25°C)/0.005 m
Q/t = 3.88 x 10^4 W or 38.8 kW

However, we need to convert this to kilowatts:

Q/t = 38.8 kW

Therefore, the answer is C, 4.84 kW.
