Chapter 2 Flashcards
includes anything whose thermodynamic properties are of interest
thermodynamic system
It is embedded in its surroundings or environment; it can exchange heat with, and do work on its environment through a boundary.
thermodynamic system
thermodynamics system classifications
open
closed
isolated
can exchange both energy and matter with its surroundings
open system
can exchange only energy not matter
closed
cannot exchange energy and matter
isolated system
occurs between the system and its surroundings in the form of heat and work
energy transfer
In this, the thermodynamic properties within a control volume do not change with respect to time; but they do not need to remain uniform everywhere within the control volume.
steady flow
If neither the mass nor the energy within the control volume change with respect to time, the flow is called
steady flow
one of the most fundamental principles in nature. even chemical equations are balanced based on this.
conservation of mass principle
this principle is considering the amount of mass entering and leaving the system using mass balance equation
