Questions and Answers
An open system is a system with mass flow through the boundary. Surroundings: everything external to the system (the system is separated from the surroundings by the system boundary). Isolated system: a closed system without any interaction with its surroundings. ┌ Macroscopic point of view: the gross or overall behavior. └ Microscopic point of view: statistical behavior of particles. Property: a macroscopic characteristic of a system that is independent of path (or process), e.g., temperature, pressure, density, etc. ┌ Intensive property: its value is independent of the size or extent of how much │ you take in a system. │ For example, pressure, temperature, density, etc. └ Extensive property: its value depends on the size or extent of how much you take in a system, e.g., mass, volume, energy. State: the condition of a system as described by its properties. Process: the path of the succession of states through which the system passes (or, simply, the path of transformation from one state to another). Steady state: the state for which the system’s properties do not change with time. Thermodynamic cycle: a sequence of processes that begins and ends at the same state. Phase: a quantity of matter that is homogeneous chemically and physically, e.g.
