Question: 1 L2 ASSIGNMENT 2 PART 1 Th k k - To C Two slabs of the same area A =690 cm, and the thickness

1 L2 ASSIGNMENT 2 PART 1 Th k k - To C Two slabs of the same area A =690 cm, and the thickness L=7cm and L=17cm and thermal conductivities k=7W/m C and k=23W/m C are in thermal contact with each other as shown. The temperatures of their outer surfaces are Tc = -20C and Th=21.5C respectively. Determine the temperature at the interface. State your answer in C to the nearest 0.1C. Take 0C-273K.
