Liquids expand when its atoms vibrate faster about their fixed points, but because the bonds between separate molecules are usually less tight they expand more than solids. This is the principle behind liquid-in-glass thermometers. An increase in temperature results in the expansion of the liquid which
This thermal expansion calculator uses the most common formula used to estimate the expansion caused by a change in temperature. The linear thermal expansion equation calculates the increase or decrease in a single dimension of a body as a result of a change in temperature, it is calculated by multiplying the dimension of the material by the Coefficient of Linear Thermal Expansion for that Thermal Expansion Coefficient and Youngs Modulus of mechanical, thermal, electrical, and viscoelastic properties has been done through the reinforcing filler such as carbon nanotubes, nanofibers, various particles, and so on.
