Macroscopic and Microscopic Approaches | Concept of continuum
Macroscopic and Microscopic Approaches The behaviour of matter can be studied by two approaches 1. Macroscopic approach, 2. Microscopic approach 1. Macroscopic approach – In the macroscopic approach a certain quantity of matter is considered for study without knowing the behaviour of individual…
State ,Path and Process in Thermodynamics | Thermodynamics Cycle
State, path and process State A state is condition of system and is specified by its properties. At a given state all the properties of a system have definite values Path Change of state of a system is the consequence of any operation in which properties will change. The series of states through which system…
Function as a Correspondence
Function as a correspondence Let A and B be two non-empty sets. Then a function ‘f ‘ from set A to set B is a rule or method or correspondence which associates elements of set A to elements of set B such that: Fig. 2(a) (i) all elements of set A are associated to…
Complement of a Set
Complement of a set Let U be the universal set and let A be a set such that A ⊂ U. Then the complement of A with respect to U is denoted by A’ or Ac or U-A and is defined the set of all those elements of U which are not in A. Thus…
Types of Thermodynamic System | Homogeneous and Heterogeneous Thermodynamic System
Thermodynamic system Thermodynamic system is defined as quantity of matter or a region in a space chosen for study. Everything external to the system is called surroundings. The system is separated from the surroundings by the boundary that may be real or imaginary The boundary does not intervene between the system and surroundings. It only…
First Law for a Closed System Undergoing a Quasi-static process
First Law for a Closed System Undergoing a Quasi-static process In many occasions it is necessary to consider a system undergoing a process rather than a cycle. The equation, ∮ dQ − ∮ dW = 0 is applicable during the system undergoing a cycle, and algebraic sum of all energies transfer across the system boundary…
