adiathermic (adjective), more adiathermic, most adiathermic
Characteristic of something that is not capable of transmitting radiant heat: The plumber installed adiathermic pipes in the basement of the building.
aerothermodynamics (s) (noun) (no pl)
The scientific research of the thermodynamic characteristics of gases: Aerothermodynamics is the branch of dynamics dealing with the relationship between heat and mechnical energy in the air and other gases.

Aerothermodynamics also pertains to the thermodynamic effects of air.

aerothermotherapy (s) (noun), aerothermotherapies (pl)
Treatment with currents of hot air: Aerothermotherapy is the therapeutic use of warmed air currents conveyed over the surface of the body.
An organism having a body temperature determined largely by the ambient or surrounding temperature.
A process by means of which high temperatures are produced by the combination of aluminium and oxygen.
1. In geology, a postglacial period extending from about 10,000 to 7,500 years ago, during which temperatures generally rose following the last major continental glacier advance.
2. Of or relating to any period during which temperatures are/were rising.
