Abstract
In the present paper, three phase transitions in solid methane are considered: low-temperature (under pressure), orientational phase, and high-temperature quantum-classical. It is demonstrated that the last of them has a stronger influence on physical parameters of solid methane in comparison with second-order phase transition although is not a phase transition. According to literature sources, the temperature dependence of thermal capacity of solid methane is irregular and has data lacune in the temperature range of high-temperature transition.
