## GATE Thermodynamics Syllabus (XE_E) 2024

GATE Thermodynamics Syllabus (XE_E) consists of Seven Section, consists of Basic Concepts, First Law of Thermodynamics, Second Law of Thermodynamics,  Properties of Pure Substances,  Thermodynamic Relations,  Thermodynamic Cycles,  Ideal Gas Mixtures.

### Basic Concepts

Continuum and macroscopic approach; thermodynamic systems (closed and open); thermodynamic properties and equilibrium; state of a system, state postulate for simple compressible substances, state diagrams, paths and processes on state diagrams; concepts of heat and work, different modes of work; zeroth law of thermodynamics; the concept of temperature.

### First Law of Thermodynamics

Concept of energy and various forms of energy; internal energy, enthalpy; specific heats; first law applied to elementary processes, closed systems and control volumes, steady and unsteady flow analysis.

### Second Law of Thermodynamics

Limitations of the first law of thermodynamics, concepts of heat engines and heat pumps/refrigerators, Kelvin-Planck and Clausius statements and their equivalence; reversible and irreversible processes; Carnot cycle and Carnot principles/theorems; thermodynamic temperature scale; Clausius inequality and concept of entropy; microscopic interpretation of entropy, the principle of increase of entropy, T-s diagrams; second law analysis of control volume; availability and irreversibility; third law of thermodynamics.

### Properties of Pure Substances

Thermodynamic properties of pure substances in solid, liquid and vapour phases; P-vT behaviour of simple compressible substances, phase rule, thermodynamic property tables and charts, ideal and real gases, ideal gas equation of state and van der Waals equation of state; law of corresponding states, compressibility factor, and generalized compressibility chart.

### Thermodynamic Relations

T-ds relations, Helmholtz and Gibbs functions, Gibbs relations, Maxwell relations, Joule-Thomson coefficient, coefficient of volume expansion, adiabatic and isothermal compressibilities, Clapeyron and Clapeyron-Clausius equations.

### Thermodynamic Cycles

Carnot vapour cycle, ideal Rankine cycle, Rankine Reheat cycle, air-standard Otto cycle, air-standard Diesel cycle, air-standard Brayton cycle, vapour-compression refrigeration cycle.

### Ideal Gas Mixtures

Dalton’s and Amagat’s laws, properties of ideal gas mixtures, air-water vapour mixtures and simple thermodynamic processes involving them; specific and relative humidities, dew point and wet bulb temperature, adiabatic saturation temperature, psychrometric chart.

## Conclusion

Candidates are recommended to perform a diligent analysis of their syllabus. In the GATE examination, we advise you to focus on the syllabus and prepare a strategy accordingly. Take as many mock tests as possible. They help you to understand your weaknesses and strengths.

Be consistent and stick to a healthy routine.
