Einstein theory of specific heat

Physics

A theory of the specific heat of solids proposed by Albert Einstein in a paper published in 1907. In this theory, Einstein attributed the specific heat of solids to the vibrations of the solid and made the simplifying assumption that all the vibrations have the same frequency. This theory was partially successful since it was able to derive Dulong and Petit’s law at high temperatures and showed that the specific heat capacity goes to zero as the absolute temperature also goes to zero. A better description of the specific heat of solids was given by the more realistic Debye theory of specific heat.

Chemistry

A theory of the specific heat capacity of solids put forward by Albert Einstein in 1907, in which it was assumed that the specific heat capacity is a consequence of the vibrations of the atoms of the lattice of the solid. Einstein assumed that each atom has the same frequency ν‎. The theory leads to the correct conclusion that the specific heat of solids tends to zero as the temperature goes to absolute zero, but does not give a correct quantitative description of the low-temperature behaviour of the specific heat capacity. In the Debye theory of specific heat, and in other analyses of this problem, Einstein’s simplifying approximation was improved on by taking account of the fact that the frequencies of lattice vibrations can have a range of values.

Chemical Engineering

A theory presented by Albert Einstein that proposes that the specific heat of solids is a consequence of the vibrations of the atoms in a lattice structure. The theory correctly shows that when the temperature tends towards absolute zero, the specific heat of solids tends to zero.
