A wall is made of a substance whose thermal conductivity is .93 J / (m sec Celsius). What is the outside temperature of the wall if its thickness is 30 cm and its cross-sectional area 73 m^2, and if thermal energy flows through the wall at a rate of 30 watts when the inside temperature is 28 Celsius?
After attempting to work through this i think the change in temp is .1326 degrees but im not sure, also not sure if that would mean the outside temp is .1326 lower or higher than inside. please help
