Question 2
What is the steady state rate of heat flow through a pane of glass that is 40.0 cm by 30.0 cm with a thickness of 4.00 mm when the outside temperature of the glass is -10.0C and its inside temperature is 25.0C?
The thermal conductivity of glass is 0.105 W/(mK), the specific heat of glass is 0.180 cal/(gC), and 1 cal = 4.190 J.
A) 3.81 W B) 110 W C) 24.2 W D) 47.3 W E) 18.6 W
