(43 cards)
A set of particles or interacting components considered to be a distinct physical entity for the purpose of study
System
The combination of conditions and influences outside a system that affect the behavior of the system
Environment
A thermodynamic process that takes place at constant volume so that no work is done on or by the system
Isovolumetric process
