A thermodynamic system is defined as a quantity of matter or a region in a space upon which attention is concentrated in the analysis of a problem.
There are three classes of systems:
- Closed system
- Open system
- Isolated system
Closed system: The system of fixed mass is called the closed system. There is no mass transfer across the system boundary. The energy transfer into or out of the system may happen.
The arrangement of a piston-cylinder with a certain quantity of fluid is an example of a closed system.
Open system: The open system is one in which matter crosses the boundary of the system. The energy transfer into or out of the system may happen.
Most of the engineering devices are open systems, Air compressors, turbines, pumps, etc., are examples of the open system.
Isolated system: The isolated system is one in which there is no interaction between the system and surroundings. It is of fixed mass and energy, and there is no mass or energy transfer across the system boundary.
A thermos flask and the universe is the example of an isolated system.

An open system is one in which ______.a)Mass does not cross boundarie...
An open system is a concept used in the field of thermodynamics to describe a system that can exchange both energy and matter with its surroundings. In other words, in an open system, both energy and mass can cross the boundaries of the system.
Explanation:
1. Definition of an open system:
- An open system is a system that can interact with its surroundings by exchanging energy and matter.
- It allows for the transfer of both energy and mass across its boundaries.
2. Comparison of options:
a) Mass does not cross boundaries of the system, though energy may do so
- This option describes a closed system, not an open system.
- In a closed system, energy can cross the boundaries, but mass cannot.
b) Neither mass nor energy crosses the boundaries of the system
- This option describes an isolated system, not an open system.
- In an isolated system, neither energy nor mass can exchange with the surroundings.
c) Both energy and mass cross the boundaries of the system
- This option accurately describes an open system.
- In an open system, both energy and mass can transfer across the system boundaries.
d) Mass crosses the boundary but not the energy
- This option describes a closed system, not an open system.
- In a closed system, mass can cross the boundaries, but energy cannot.
3. Importance of an open system:
- An open system is important in many natural and engineering processes.
- Examples of open systems include living organisms, rivers, and some industrial processes.
- These systems allow for the exchange of energy and matter, enabling them to maintain a steady state and respond to external influences.
In conclusion, an open system is one in which both energy and mass can cross the boundaries of the system. This distinguishes it from closed and isolated systems, where only one or neither of these exchanges is possible.
