1. You'd have to add heat at precisely the same rate that the gas is doing work.
An isothermal PV diagram illustrates a thermodynamic process where the temperature remains constant.
An isothermal process takes place at a constant temperature so that the internal energy of a system remains unchanged. For ideal gases, this usually occurs under conditions where heat exchange occurs with the surroundings to maintain a constant temperature.
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.
Reversible adiabatic expansion/compression
Isentropic enthalpy is a measure of energy in a system that remains constant during an isentropic process, which is a thermodynamic process where there is no change in entropy. In thermodynamic processes, isentropic enthalpy helps to analyze the energy changes that occur without considering any heat transfer or work done.

Isothermal process is a process in which change in pressure and volume takes place at a constant temperature.
Temperature is constant.ΔU = 0 W=Q
Reversible adiabatic expansion/compression
The adiabatic process graph shows that as temperature increases, pressure also increases in a thermodynamic system. This relationship is due to the fact that in an adiabatic process, no heat is exchanged with the surroundings, so changes in temperature directly affect pressure.
At engineering level technically both process are same except there definition both process give hyperbolic curve in P-V diagram and straight line in T-S diagram. and even in polytropic process PV^n=constant if n=1 then it is not hyperbolic process it is isothermal process even though the definition says pv=c is hyperbolic process.

In a thermodynamic process, the work done on the system is equal and opposite to the work done by the system. This is based on the principle of conservation of energy, where the total work done in a closed system remains constant.

Temperature is constant during an isothermal process. The work done (W) is equal to the heat added (Q). The change in internal energy (ΔU) is zero for an isothermal process. The pressure can vary during an isothermal process, depending on the specific conditions.
