Thermodynamics (Hindi)

Learn the basics of thermodynamics by defining system, surroundings, and universe, and exploring open, closed, and isolated systems, with boundaries and the relationship between heat and mechanical work.

Classify systems as open, closed, or isolated, and homogeneous vs heterogeneous; compare macroscopic and microscopic perspectives and distinguish intensive, extensive, and specific properties.

Explore the state of a system in thermodynamics, defined by pressure, volume, and temperature, and analyze thermodynamic processes and cycles that drive state changes.

Define absolute pressure, gauge pressure, atmospheric pressure, and vacuum, and compare their meanings and practical implications in thermodynamics.

Explore the laws of perfect gases, including Boyle's law and Charles's law, and apply the ideal gas equation to relate pressure, volume, and temperature.

Explore specific heat at constant volume and constant pressure, and how the heat required to raise one kilogram by one degree uses cv and cp values.

Apply the ideal gas law to solve numerical problems, calculating pressure, mass, and density for gases using volume, temperature, molar mass, and the universal gas constant.

Explore thermodynamics through isochoric and isobaric processes, analyzing volume and pressure changes, heat transfer, and the role of internal energy in gas behavior.

Explains the isothermal process, where temperature remains constant while pressure and volume change, and demonstrates how the area under the pv diagram represents work.

Explore thermodynamics through numerical problems on air in pistons, comparing constant pressure and constant volume processes, calculating Cp, Cv, gamma, work, and entropy changes.

Study isentropic processes where the system's entropy remains constant along a reversible path. Explore how a frictionless gas piston transfers heat and work to sustain that constant entropy.

Explore how gas behavior changes during thermodynamic processes by examining pressure, volume, and temperature relationships, including compression and the pressure–volume relationship in Kelvin-scale terms.

Explore how the first law of thermodynamics and the steady flow energy equation govern energy conservation, linking heat, work, and changes in internal, kinetic, and potential energy.

Explore the second law of thermodynamics, defining why a perpetual motion machine is impossible and why heat cannot all be converted into work from a single heat source.

Explore the zeroth and third laws of thermodynamics, explaining thermal equilibrium, entropy behavior at absolute zero, and how temperature defines pure substances.

Explore heat transfer concepts and the first law of thermodynamics in steady-flow systems. Solve boiler and turbine problems using enthalpy, pressure–volume relations, and numerical methods.
