Consider two cylindrical metal rods withequal cross section—one lead, the other aluminum—connected inseries. The temperature at the lead end of the rods is 22.5 °C; thetemperature at the aluminum end is 85.0 °C. (a) Given that the temperature at the lead-aluminum interface is 52.5 °C, and that the leadrod is 14.5 cm long, what condition can you use to find the length ofthe aluminum rod? (b) Find the length of the aluminum rod
Energy transfer
The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.
Molar Specific Heat
Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)
Thermal Properties of Matter
Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which is transferred between the two systems or in between the systems and their surrounding by the virtue of difference in temperature. Calorimetry is that branch of science which helps in measuring the changes which are taking place in the heat energy of a given body.
