An engineer is investigating energy loss through windows. The windowpane of interest is 0.650 cm thick, has dimensions of 1.19 m

krok68 [10]

Answer:

7908.92307 W

683330953.248 J

Explanation:

k = Heat conduction coefficient = 0.8 W/(m·°C)

A = Area = $1.19\times 2.25\ m^2$

l = Thickness = 0.65 cm

$T_2$ = 24°C

$T_1$ = 0°C

Rate of heat transfer is given by

$Q=\frac{kA(T_2-T_1)}{l}\\\Rightarrow Q=\frac{0.8\times 1.19\times 2.25(24-0)}{0.65\times 10^{-2}}\\\Rightarrow Q=7908.92307\ W$

The rate of heat transfer is 7908.92307 W

Amount of energy is given by

$E=Qt\\\Rightarrow E=7908.92307\times 24\times 3600\\\Rightarrow E=683330953.248\ J$

The energy transferred through the window in one day is 683330953.248 J

Avogadro’s law and charles’s law describe a proportionality of the volume of a gas when the pressure is constant. Describe the p

yaroslaw [1]

Answer:PV/T

Explanation:Here, PV / T = k shows how pressure, volume and temperature relate to each other, where k is a constant number.

The formula for the combined gas law can be adjusted to compare two sets of conditions in one substance. P1V1 / T1 = P2V2 / T2
