# Awindowpane is half a centimeter thick and has an area of 0.7 m2. the temperature difference between the inside and outside surfaces of the pane is 15 °c. what is the rate of heat flow through this window? (thermal conductivity for glass is 0.84 j/s⋅m⋅°c.) ​ select one: a. 3,600 j/s b. 2,100 j/s c. 1,180 j/s d. 1,800 j/s e. ​1,400 j/s

The answer is d. 1800 J/s.

Step-by-step explanation:

The given quantities are:

d = 0.5 cm = 0.005 m               (thickness of the windowpane)

A = 0.7 m²                                  (area of the windowpane)

ΔT = 15 °C                                  (temperature difference)

k = 0.84 J/s·m·°C                       (thermal conductivity)

To get the rate of heat flow, we must use the equation: Substituting all the given quantities, we get:  rounding off we get I hope this helps.
