Definition of thermal expansion
WebJan 28, 2024 · Thermal expansion occurs in one, two, and three dimensions. Linear thermal expansion is characterized by an increase in length. For solids, length either … WebThe coefficient of thermal expansion is also often defined as the fractional increase in length per unit rise in temperature. The exact definition varies, depending on whether it is specified at a precise temperature (true coefficient of thermal expansion or α− or over a temperature range (mean coefficient of thermal expansion or α).

A gas expands when heated and condenses when cooled. Charles' Law predicts a four-fold decrease in the volume of a gas that is cooled from room temperature to the temperature of liquid nitrogen (77 K). If the gas inside the balloon condenses into a volatile liquid at or around 77 K, the volume change will be even larger. …
