Answer:
Explanation:
Thermal conductivity of glass pane = .8 W / m K
For conduction of heat , the formula is as follows
Q = [tex]\frac{kA(T_1 - T_2 )t}{d }[/tex] ; Q is heat conducted in time t by a medium of thickness d , area of cross section A and ( T₁ - T₂ ) is the temperature difference .
Putting the values in the equation
Q = [tex]\frac{.8 \times32\times(25 - 0 )\times1}{.0062 }[/tex]
= 103225.8 W
b )
energy lost in one day
= 103225.8 x 24 x 60 x 60
= .89187 x 10¹⁰ J .
