Extracted text: A room is constructed using 3 different layers of different materials. The materials with their thermal conductivities are given in the table below: Conductivity, m -K W Thickness, mm Inner layer 0.151 12.7 Middle layer 0.0433 101.6 Outer layer 0.762 76.2 The temperature inside and outside of the room is 255.4 K and 297.1 K. Calculate the heat loss and temperature at the interface between inner layer and middle layer. a) Q =-14.7 W and T; = 256.8 K b) Q =-43.8 W and T; = 255.4 K c) Q =-16.5 W and T; = 256.8 K d) Q =-17.3 W and T = 233.4 K
