noun
adiabatic process
Technical term in thermodynamics for a process where no heat is exchanged with the surroundings.
理想気体の断熱過程では、温度と体積の関係がポアソンの式で表される。
In an adiabatic process of an ideal gas, the relationship between temperature and volume is expressed by Poisson's equation.
Compound of 断熱 (heat insulation) and 過程 (process). The term is a direct translation of the English 'adiabatic process'.
