Thermodynamic Chapter 2 Properties Of Pure Substances Ppt This document provides an overview of properties of pure substances and phase change processes. it defines a pure substance as having a fixed chemical composition throughout. pure substances can exist in solid, liquid, or gas phases. phase change processes like melting, boiling, and condensation occur at saturation conditions where two phases. The substance is characterized by its properties. this chapter shows how this is done for two major behavioral classes of substance covered in this course; phase change fluids, and gases. pure substance • 3 major phases of pure substances; • solid • liquid • gas • plasma.
Thermodynamic Chapter 2 Properties Of Pure Substances Ppt A substance that has uniform thermodynamic properties throughout is said to be homogeneous. pure substance a pure substance has a homogeneous and invariable chemical composition and may exist in more than one phase. examples: 1. water (solid, liquid, and vapor phases) 2. mixture of liquid water and water vapor 3. carbon dioxide, co2 4. nitrogen. Chapter 2 properties of pure substance. 1. pure substance a substance that has a fixed chemical composition throughout is called a pure substance. water nitrogen air helium carbon dioxide pure substance may exist in different phases, but the chemical compositions is the same. No headers. this chapter introduces thermodynamic properties, phase diagrams, and thermodynamic tables of pure substances. students will learn how to determine thermodynamic properties of pure substances by using thermodynamic tables, and how to illustrate states and processes in phase diagrams. Properties of pure substances (motivation) to quantify the changes in the system, we have to be able to describe the substances which make up the system. the substance is characterized by its properties. this chapter shows how this is done for two major behavioral classes of substance covered in this course; phase change fluids, and gases.

Phase equilibrium in our prior lesson, we studied the phase change of water as it moved from a pure liquid phase at to a pure vapor, as illustrated in the left figure. the temperature is plotted as a function of specific volume for various pressures in the figure on the right. note that the horizontal axis has a logarithmic scale. state 1 is called a “compressed liquid” or a “sub cooled. 2.1 properties. substances have properties that are used to identify and describe them. you should be familiar with four properties from everyday life: temperature, pressure, volume and mass. we measure the amount of milk by volume and meat by mass. we quantify the “hotness” or “coldness” of air by measuring its temperature.
