A heat-conducting sphere of radius a is composed of two hemispheres with an insulating infinitesimal space between them, as shown in the figure. The upper and lower halves of the sphere are in contact with thermal T, baths of temperatures +T, and -T, respectively. The sphere of radius a is inside another heat-conducting sphere of radius b with a temperature T2 +T -TV Calculate the temperature at the points: a) Within the inner sphere, b) In the region between the two spheres Figure: The hemispheres of the inner sphere are at different c) Outside the outer sphere temperatures

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.
