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

6 identical rods of same material are kept as shown in figure. The ends A and B are maintained at 60∘C and 0∘C respectively. The temperature of point Q will be

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)

A brass rod with a length of 20.0 cm is placed side by side with an aluminum rod with a length of 20.0 cm, and this system is placed between a hot temperature of 150 °C and a cold temperature of −10.0 °C. The thermal conductivities of the brass and the aluminum are 100 W/m °C and 230 W/m °C, respectively. The rods have the same cross-sectional area of 20.0 cm2. What is the rate of heat flow from the hot temperature to the cold temperature?

1. A brass rod is 2m long at a certain temperature. What is itslength for a temperature rise of 100k if the expansivity ofbrass is 1.8 x ?2. The linear expansivity of a material of a cube is 1.2 x10 -6 K -1 .If the length of each side of the cube is 10cm, find the areaof one face of the cube and the volume of the cube whenits temperature is raised by 30k.
