Abstract
Altitude and temperature dependences of inhomogeneous substance heat capacity have been studied in the gravitational field of the Earth in the vicinity of critical point on the basis of the fluctuation theory of phase transitions and the theory of gravitational effect. The obtained data prove non-monotonous field and temperature dependences of heat capacity of spatially inhomogeneous substance that is supported by experimental research of heat capacity in macro and confined systems under terrestrial conditions and at space flight microgravitation.
