Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

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 micro-gravitation.
