Thermodynamic Systems and Properties: Fundamentals Of Engineering Thermodynamics 8th Edition Solutions
Thermodynamics deals with the study of energy and its transformations. A thermodynamic system is a collection of matter that is being studied. Systems can be classified as open, closed, or isolated based on their ability to exchange mass and energy with the surroundings.
Properties are characteristics of a system that can be used to describe its state. Intensive properties are independent of the amount of matter in the system, while extensive properties depend on the amount of matter.
Types of Thermodynamic Systems
- Open system:Can exchange both mass and energy with the surroundings.
- Closed system:Can exchange energy but not mass with the surroundings.
- Isolated system:Cannot exchange mass or energy with the surroundings.
Examples of Intensive and Extensive Properties
- Intensive:Temperature, pressure, specific volume
- Extensive:Mass, volume, energy
The First Law of Thermodynamics
The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or transformed. This law can be expressed mathematically as:
ΔU = Q – W
where ΔU is the change in internal energy, Q is the heat added to the system, and W is the work done by the system.
Examples of Processes Involving Heat Transfer, Work, and Changes in Internal Energy, Fundamentals of engineering thermodynamics 8th edition solutions
- Isothermal process:Temperature remains constant (ΔU = 0)
- Adiabatic process:No heat is transferred (Q = 0)
- Isobaric process:Pressure remains constant (W = -PΔV)
- Isochoric process:Volume remains constant (W = 0)
Frequently Asked Questions
What is the difference between an open and a closed thermodynamic system?
An open system can exchange both mass and energy with its surroundings, while a closed system can only exchange energy with its surroundings.
What is the significance of the second law of thermodynamics?
The second law of thermodynamics establishes the concept of entropy, which measures the disorder or randomness of a system, and states that the total entropy of an isolated system can never decrease over time.
How is the first law of thermodynamics related to the conservation of energy?
The first law of thermodynamics states that the total energy of an isolated system remains constant, which is consistent with the principle of conservation of energy.
