What is the work done in an isothermal process?

For an ideal gas, from the ideal gas law PV = NkT, PV remains constant through an isothermal process. A curve in a P-V diagram generated by the equation PV = const is called an isotherm. For an isothermal, reversible process, the work done by the gas is equal to the area under the relevant pressure -volume isotherm.

What is isothermal process isochoric process and isobaric process?

An isothermal process, during which the system’s temperature remains constant. An adiabatic process, during which no heat is transferred to or from the system. An isobaric process, during which the system’s pressure does not change. An isochoric process, during which the system’s volume does not change.

In which process work done is maximum isothermal or isobaric?

In an isothermal process all heat is converted into work while in an isobaric process heat is converted into work as well as internal energy. However, the PV-graph shows that the maximum work is done in an isobaric process.

What is the work done in isobaric process?

An isobaric process occurs at constant pressure. Since the pressure is constant, the force exerted is constant and the work done is given as PΔV. An isobaric expansion of a gas requires heat transfer to keep the pressure constant.

What is isothermal process derive the expression for work done in isothermal process?

Let us consider 1 mole of gas is enclosed in an isothermal container. Let P1,V1 and T be the initial pressure, initial volume, and temperature. As work is done, let the gas expand to P2,V2 where P2 is the reduced pressure and V2 is the expanded volume. ⇒PV=RT (∵n=1mole) and R is the ideal gas constant.

What is isothermal and isochoric process?

Isothermal process is a thermodynamic process where temprature remains constant. Isobaric process is a thermodynamic process where pressure remains constant. Isochoric process is a thermodynamic process where volume remains constant.

Why work done in isothermal process is greater than isobaric process?

Some heat is used to increase the enthalpy of the system and remaining heat is converted into heat. Therefore work is higher in isothermal process than isobaric process.

Is work done in an isobaric process?
