What is the difference between isobaric and isochoric process?
An isobaric process is a thermodynamic-processin which the pressure stays constant: Δp = 0 The term derives from the Greek isos, meaning "equal," and barus, "heavy." The heat transferred to the system does work but also changes the internal energy of the system:
What is isobaric process?
An isobaric process is a thermodynamic process that occurs at a constant pressure. This means that the system is allowed to exchange heat with its surroundings but the pressure remains the same throughout the process. In an isobaric process, the work done is determined by the change in volume of the system.
How much work is done by the gas during this expansion?
The work done by the gas during the expansion is equal to the area under the pressure-volume curve on a graph of the process.
What is the relationship between the work done during an isothermal expansion and the change in internal energy of a system?
During an isothermal expansion, the work done is equal to the change in internal energy of the system.
What is the relationship between the work done and the expansion of gas in a thermodynamic system?
The work done in a thermodynamic system is directly related to the expansion of gas. When gas expands in a system, it can perform work by pushing against a piston or moving a turbine. This work done is a result of the gas expanding and exerting a force on its surroundings.
What is isobaric pressure?
constant pressure where Work is done through P(Vf-Vi)

Work done is not a state function?
In mechanics,work done(work=force.displacement of body) by a body is independent of path.It only depends on the initial and final state of the body.However in thermodynamics,the work done by an ideal gas(work=pressure.change in volume of gas) depends on the path taken(isochoric,isothermal,isobaric,adiabatic)

What is free expansion in thermodynamics?
In free expansion, the external pressure is zero, i.e. work done is zero. Accordingly, free expansion is also called irreversible adiabatic expansion.
How does work play a role in an adiabatic expansion process?
In an adiabatic expansion process, work is done by the gas as it expands without gaining or losing heat from its surroundings. This work is done against the external pressure, causing the gas to decrease in temperature and increase in volume. The work done in this process is equal to the change in internal energy of the gas.
Work done in a free expansion process is?
In a free expansion process, no work is done because there is no external pressure or constraint on the system. The gas expands into a vacuum freely without any opposing force to overcome, resulting in no work being performed.
What is the relationship between reversible adiabatic expansion work and the change in internal energy of a system?
During reversible adiabatic expansion, the work done by the system is equal to the change in internal energy.
What is the relationship between enthalpy and the isothermal expansion process?
In an isothermal expansion process, the enthalpy remains constant. This means that the heat energy exchanged during the expansion is equal to the work done by the system.
