Final volume (given volumetric thermal expansion coefficient,initial volume,temperature)
final volume, volume after the change of temperature
volumetric thermal expansion coefficient
initial volume, volume before the change of temperature
Thermal expansion is the tendency of matter to change in volume in response to a change in temperature. When a substance is heated, its particles begin moving more and thus usually maintain a greater average separation. Materials which contract with increasing temperature are rare; this effect is limited in size, and only occurs within limited temperature ranges. The degree of expansion divided by the change in temperature is called the material's coefficient of thermal expansion and generally varies with temperature. The thermal volumetric expansion coefficient measures the fractional change in an object's volume per degree change in temperature at a constant pressure.
