Homework Statement
A double paned window consists of two glasses and a gap between them. The inner glass is d1 = 6mm thick, the gap is D = 16mm thick and the outer glass is d2=4mm thick. The inside temperature (by the inner glass) is T1=23°C and the outside temperature is T2=-10°C. What is the temperature of the gas in the gap? Glass conductivity is k=0.96 W/(m*K)
Homework Equations
[itex]\frac{\Delta Q}{\Delta t} = kA\frac{\Delta T}{L}[/itex]
The Attempt at a Solution
I tried doing something like this: since we don't know area or time, but they are the same to both of the glasses, expressing them from the euation and then equating might work. But that's where I'm stuck: [itex]\frac{\Delta Q_1 d_1}{\Delta T_1 k} = \frac{\Delta Q_2 d_2}{\Delta T_2 k}[/itex]. Not sure what to do next .. Also, there might be a trick that we don't know what is the gas between the glasses - it's not necessarily air..
