#thermodynamicschemistry #animatedchemistry #kineticschool • Basic Concepts of Thermodynamics (Animation) • Chapters: • 0:00 Kinetic school's intro • 0:17 Definition of Thermodynamics • 0:52 Thermodynamics terms • 1:40 Types of System • 2:40 Homogenous and Heterogenous System • 3:55 Thermodynamic Properties • 6:30 State of a System • 8:10 State Function • 9:25 Path Function • • Thermodynamics: • The word thermodynamics was derived from the Greek words: • Thermé which means “Heat” and Dynamics means “force”. • So, Thermodynamics is essentially the study of forces due to heat or heat due to forces. • THERMODYNAMIC TERMS: • System: A thermodynamic system (simply system ) is that part of the universe which is under thermodynamic study. • Surroundings The space outside the thermodynamic system is known as the surroundings. • System Boundary: Anything which is separating the system from the surroundings, is called the boundary. • Thermodynamics systems can be described in three different ways: • Open, Closed And isolated. • • THERMODYNAMICS Properties: • • Thermodynamic properties are defined as characteristic features of a system, capable of specifying the system's state. • In general, thermodynamic properties can be divided into two general classes: • Intensive properties and Extensive properties. • State Variable: • When the properties of a system define the state of that system is called State Variables. • State function: • A State function is a thermodynamic property of a system, whose value depends only on the present state of the system and is independent of the path by which that state was reached. • Path function: • A Path function is a thermodynamic property of the system, whose value depends upon the path by which the system changes from its initial to final states.
