We show that macroscopic thermodynamical properties - such as functions of
internal energy and magnetization - can detect quantum entanglement in solids
at nonzero temperatures in the thermodynamical limit. We identify the parameter
regions (critical values of magnetic field and temperature) within which
entanglement is witnessed by these thermodynamical quantities.
