Have you ever noticed that small gap in the railway tracks? Why do you think they are there? Or, have you ever noticed your mom trying to open up a jammed bottle, by heating up near its neck? What is this magic all about? If the temperature increases, then the volume of the material also increases. Generally, this is known as thermal expansion.

Thermal expansion is the tendency of matter to change in volume in response to a change in temperature. An example of this is the buckling of railroad track, as seen in. Atoms and molecules in a solid, for instance, constantly oscillate around its equilibrium point. This kind of excitation is called thermal motion. When a substance is heated, its constituent particles begin moving more, thus maintaining a greater average separation with their neighboring particles. Fig 1 : Thermal expansion of long continuous sections of rail tracks is the driving force for rail buckling. This phenomenon resulted in train derailments during — in the US alone.

Directly proportional to the original length l 0. This is an expression for the coefficient of linear expansion of a solid. This is an expression for the coefficient of superficial expansion of a solid. Experimentally it is found that the change is volume V — V 0 is. This is an expression for the coefficient of cubicalexpansion of a solid. Thus the coefficient of superficial expansion is twice coefficient of linear expansion.
