Two rods one made of copper and other made of steel of the same length and same cross-sectional area are joined together. The thermal conductivity of copper and steel are 385Js−1K−1m−1) and 50Js−1K−1m−1, respectively. The free ends of copper and steel are held at 100°C and 0° C, respectively. The temperature at the junction is, nearly

Rachel performed an investigation to study the thermal conductivity of four different materials. She started with four identically shaped rods—each made of a different material. Then, she placed one end of each rod into a pot of boiling water, which was at 100°C.After five minutes, Rachel measured the temperatures of the ends of the rods that were sticking up out of the pot to see whether they got hot. Her results are shown below.Thermal Conductivity InvestigationMaterial Temperature of End of RodAfter 5 MinutesMaterial 1 41°CMaterial 2 53°CMaterial 3 98°CMaterial 4 59°CRachel knows that one of the materials is copper and that copper conducts thermal energy very well.

Three geometrically identical slabs A,B and C have thermal conductivities k,k and 3k. In any configuration of these, extreme left face is always kept at 100∘C while extreme right face is always kept at 0∘C. Consider two configurations shown.The difference (in ∘C) of temperatures of mid-points of the two configurations is 100n . Find n.

17. An aluminum rod of length 1.8cm at 100C is heated to produce a difference in length of 0.007m. Calculate the temperature to which it is heated (Liner expansivity of aluminum= 2.3 x 10-5 K-1)
