Answer in brief.
Why should a Carnot cycle have two isothermal two adiabatic processes?
State the assumptions made for thermodynamic processes.
Explain the cyclic process.
Explain the thermodynamics of the isobaric process.
Derive the work done in an isothermal process.
Derive the work done in an adiabatic process.
Assertion: Equal volumes of monatomic and polyatomic gases are adiabatically compressed separately to equal compression ratio `("P"_2/"P"_1)`. Then monatomic gas will have greater final volume.
Reason: Among ideal gases, molecules of a monatomic gas have the smallest number of degrees of freedom.
In the figure shown here, the work done in the process ACBA is ______.
In a certain thermodynamical process, the pressure of a gas depends on its volume as kV3. The work done when the temperature changes from 100°C to 300°C will be ______ nR, where n denotes number of moles of a gas.
Explain the thermodynamic process.
