The diagram above shows an experimental investigation on the movement of thermal energy by conduction. If the heat source were turned off, what would happen to the temperature of the rod?

If the heat source were turned off, what would happen to the temperature of the rod?

The ends of a uniform metal rod of length 100 cm and area of cross-section 2 cm2 are maintained at 0 °Cand 100 °C. At the mid point of the rod, heat is supplied at a constant rate of 40Js−1. If the temperature gradient on the higher temperature side of the rod in steady state is 50 x° cm−1, then the value of x is (Thermal conductivity of the metal =400 J s−1 m−1 K−1)Your Answer IncorrectCorre

What will happen when heat transfers through conduction?

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.

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
