Definition of thermal expansion
WebTools. In mechanics and thermodynamics, thermal stress is mechanical stress created by any change in temperature of a material. These stresses can lead to fracturing or plastic deformation depending on the other variables of heating, which include material types and constraints. [1] Temperature gradients, thermal expansion or contraction and ... Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, molecules … See more Predicting expansion If an equation of state is available, it can be used to predict the values of the thermal expansion at all the required temperatures and pressures, along with many other state functions See more When calculating thermal expansion it is necessary to consider whether the body is free to expand or is constrained. If the body is free to … See more The thermal expansion of liquids is usually higher than in solids because the intermolecular forces present in liquids are relatively weak and its constituent molecules are more … See more This section summarizes the coefficients for some common materials. For isotropic materials the coefficients linear thermal expansion α and volumetric thermal expansion αV are related by αV = 3α. For liquids usually the coefficient of volumetric … See more The coefficient of thermal expansion describes how the size of an object changes with a change in temperature. Specifically, it measures the fractional change in size per … See more Since gases fill the entirety of the container which they occupy, the volumetric thermal expansion coefficient at constant pressure, $${\displaystyle \alpha _{V}}$$, is the only one of interest. For an ideal gas, a formula can be readily obtained by … See more The expansion and contraction of the materials must be considered when designing large structures, when using tape or chain to measure distances for land surveys, when … See more
