1. Laws of Thermodynamics

The laws of thermodynamics provide a fundamental framework for understanding the behavior of energy and matter in thermodynamic systems.

First Law of Thermodynamics

• Energy cannot be created or destroyed, only transferred or transformed.
• The change in internal energy of a system is equal to the difference between the heat added to the system and the work done by the system.

Second Law of Thermodynamics

• Entropy, a measure of disorder, always increases in a closed system.
• The entropy of an isolated system approaches a maximum value as the system approaches equilibrium.

Third Law of Thermodynamics

• The entropy of a perfect crystal at absolute zero is zero.
• Absolute zero is unattainable in practice.

2. Properties of Pure Substances

Pure substances are composed of a single chemical species and exhibit distinct properties that can be characterized using thermodynamic principles.

P-v-T Behavior

• The P-v-T behavior of a pure substance can be represented by an equation of state.
• The ideal gas law is a simplified equation of state that applies to gases at low pressures and high temperatures.

Phase Rule

• The phase rule relates the number of phases, components, and degrees of freedom in a system.
• The phase rule can be used to predict the behavior of systems undergoing phase transitions.

Thermodynamic Properties

• Common thermodynamic properties of pure substances include specific volume, specific heat, and entropy.
• These properties can be used to calculate changes in state and analyze system behavior.

3. Energy Analysis of Closed Systems

Closed systems are systems that do not exchange mass with their surroundings, allowing for the analysis of energy transfer and conversion.

Internal Energy and Enthalpy

• Internal energy is a measure of the total energy of a system, including kinetic and potential energy.
• Enthalpy is a measure of the energy available for work, equal to the sum of internal energy and the product of pressure and volume.

First Law of Thermodynamics for Closed Systems, Fundamentals of thermodynamics 7th edition

• The change in internal energy of a closed system is equal to the heat added to the system minus the work done by the system.
• This principle can be used to analyze energy transfer in processes such as combustion and heat transfer.

Applications of Energy Analysis

• Energy analysis is used to design and optimize systems for energy efficiency.
• Examples include power plants, heating and cooling systems, and chemical processes.
