The volumetric expansion coefficient would be 02 for 50 C or 0004 per degree C. Our mission is to provide a free world-class education to anyone anywhere. Contraction is the reverse process.
Depending on the type of expansion thermal expansion is of 3 types Linear expansion Area expansion and Volume expansion.
A linear expansion coefficient is usually employed in describing the expansion of a solid while a volume expansion coefficient is more useful for a liquid or a gas. Expansion in physics increase in volume resulting from an increase in temperature. The expansion of alcohol in a thermometer is one of many commonly encountered examples of thermal. The coefficient cubical expansion is defined as an increase in volume per unit original volume at 0 0 c per unit rise in temperature.
