Open systems in thermodynamics allow matter as well as energy to enter and leave. For example this coffee cup is an open system when compared to the thermos. An open system on the other hand is a system that allows things such as both matter and energy to enter and leave it. An open ...
Closed systems are often associated with thermodynamics (the study of the movement of heat energy). One law of thermodynamics states that heat only travels from hot entities to cold entities unless there is 'work' to stop it. In a closed system, the heat gained by the cold object comes fro...

Thermodynamics - Work Done in a Closed System (Polytropic?) Just want to check that I've used the correct method for this thermodynamics question I've been set. Any clarification would be greatly appreciated. So I have a closed system in which a gas is compressed from a pressure of 3 bar...
ClosedSystemsThermodynamics Replies: 4 Forum:Engineering and Comp Sci Homework Help I How to determine whether a system is closed or not? I know the definition of an open/closed system but I am still confused: 1) Why isn't C a closed system? 2) I know that a simple system's state is...
of thermodynamics. As a result, these techniques may lead to biochemical reaction systems whose concentration dynamics could not possibly occur in nature. Therefore, development of a thermodynamically consistent approach for estimating the rate constants of a biochemical reaction system is highly desirable...
(0, 1), and thus, the function has neither a maximum value nor a minimum value. however, if we extend the domain of the given function f from the open interval (0, 1) to the closed interval [0, 1], then f still may not have a local maximum or minimum value. still, it ...
Surprisingly, and in accordance with the second law of thermodynamics, the latter symmetry persists even if it is broken in the microscopic quantum dynamics, for example, by an external magnetic field. By propagating r(0) backward in time (with respect to one particular U) and taking the ...
Energy analysis is based on the first law of thermodynamics and does not consider the conditions of the ambient environment in which the analyzed system or component operates [41]. In contrast to energy analysis, exergy analysis is based on the second law of thermodynamics and considers ambient ...
4. The Irreversible Trigeneration Cycles Design Based on Finite Physical Dimensions Thermodynamics The reference [15] developed the analysis of endoreversible trigeneration cycles design based on finite physical dimensions thermodynamics (FPDT). This section is extending the mathematical models to irreversible...
