When a metal is heated, its atoms vibrate more about their position in the lattice (a network of crossed bars). This causes them to take up more space, so the solid metal expands from its original shape. Calculate the heat needed to expand a ring made of copper with an internal diameter of 50mm to fit over a shaft of diameter 50.05mm. The shaft is measured at a temperature 20 degrees c

Why is metal a better conductor of heat than non-metals? In metals, apart from transferring heat energy by the relatively slow process of molecular collision, another faster process of free electron diffusion takes place. Metals contain free electrons that are mobile. When heated, these free electrons gains KE and will diffuse to the cooler end at high speeds. In the process, they will collide with atoms at the cooler end and transfer kinetic energy to them.
