Using an appropriate cyclic rule and an appropriate Maxwell relation, show that (∂P / ∂V)S = γ (∂P / ∂V)T where γ = CP / CV
admin We know that cyclic is given as: (∂P / ∂V)S (∂V / ∂S)P (∂S / ∂P)V = -1 (∂P / ∂V)S = – / = / = -/ = –…

Explain Clapeyron-Clausius Equation and also give its derivation
Clapeyron discovered an important fundamental equation which helps in finding the extensive application in one component, two phase system and by Clausius from second law of thermodynamics. Hence this fundamental…
Derive the Gibbs-Duhem Equation and give its Applications?
Gibbs-Duhem Equation The Gibbs free energy can be defined in two different ways once by subtracting off combinations of entropy S, enthalpy H and temperature T and other as a…
A mass ‘m’ of fluid at temperature T1 is mixed with an equal amount of the same fluid at temperature T2. Prove that the resultant change of entropy of the universe is: [2 mc ln (T1 + T2) / 2]/[(T1 T2)1/2]and also prove that it is always positive.
Mean temperature of the mixture = (T1 + T2) / 2 Thus change in entropy is given by: ∆S = S2 – S1) = mc (T1 + T2)/2∫ T1 (dT…
Define Thermodynamics?
Thermodynamics is a science and, an important engineering tool used to describe processes that involve changes in temperature, transformation of energy, and the relationships between heat and work. Thermodynamics where…
Explain thermodynamics system and there Types
In general, Thermodynamics involves the study of various systems. A system is a collection of objects, and there are a lot of hurdles in the way it is defined. However,…
Explain thermodynamics state of a system and state variable?
A thermodynamic state is a set of values of properties of a thermodynamic system that must be specified to reproduce the system. The individual parameters are known as state variables,…
What do you understand by thermodynamic Process? Explain its types also.
Thermodynamic process The operation by which a system changes form one state to another is called a process. Whenever a system changes from one state to another it is accompanied…
Define Reversible and Irreversible Process and give example.
There are two main types of thermodynamic processes: reversible process and the irreversible process. Irreversible Process: The process is said to be an irreversible process if it cannot return the…
What do you mean by Thermodynamic Equilibrium? What do you mean by Thermodynamic Equilibrium?
The state of a system in which properties have definite, unchanged values as long as external conditions are unchanged is called an equilibrium state. Thermodynamic Equilibrium takes place when the…
