What is another word for adiabatic process?
Pronunciation: [ˌe͡ɪdɪɐbˈatɪk pɹˈə͡ʊsɛs] (IPA) 
When discussing thermodynamics, the term "adiabatic process" refers to a transfer of energy that occurs without any heat entering or leaving a particular system. This type of process, while important in the field of physics and engineering, can be difficult to describe in layman's terms. Fortunately, there are several synonyms for adiabatic process that can help clarify the concept for non-experts. Such synonyms include "energy-conserving process," "isentropic process," and "non-dissipative process." Depending on the context and level of technicality required, any of these terms can be used interchangeably with "adiabatic process" to describe energy transfer without heat flow.
