Content to be covered * Laws of thermodynamics and their consequences Thermodynamic potentials, Maxwell relations " Chemical potential, phase equilibria Phase space, micro- and macrostates Microcanonical, canonical and grand-canonical ensembles and partition functions * Free Energy and connection with thermodynamic quantities ' First- and second-order phase transitions ' Classical and quantum statistics, ideal Fermi and Bose gases Principle of detailed balance Blackbody radiation and Planck's distribution law Bose-Einstein condensation; Random walk and Brownian motion ' Introduction to nonequilibrium processes Diffusion equation
Thermodynamics Heat Movement/ transfer Deals with energy transfer and Its effect on property of system
System Types of System 1. Open System 2. Close System 3. Isolated System 4. Adiabatic System Boundary Syste Surrounding
Property Characteristics used to describe the state or condition of the system. Eg. Pressure, temperature, composition, colour Types of Property Intensive property: independent to strength/mass. eg: density, pressure Extensive property: depend on mass/extent of system. eg: energy, entropy Process Any change in the state of system undergoes from one equilibrium to other will execute a process Types of Process * Reversible process * Irreversible process : Cyclic process * Quasi-static process
Reverible Proces as the One baclusard 2. 2. Renersilble A
Equilibrium . Absence of tendency for spontaneous change in the value of microscopi c property of system in isolated from. Thermodynamic Equilibrium When the body is in 1. Mechanical Equilibrium 2. Thermal Equilibrium 3. Chemical Equilibrium 4. Phase Equilibrium
Control volume Any region in space which is separated from its environment by a control surface which may be physical/imaginary. Steam out Water in
Concept of Continuum e A small volume of the system is compared to the whole system e This volume is bigger than the microscopic level e Allow us to treat property as a point function. e Property vary continuously in space.
