Can a process on an ideal gas be both adiabatic and isothermal. ?

The reversible expansion of an ideal gas under adiabatic and isothermal conditions is shown in the figure. Which of the following statement(s) is (are) correct?

Can two states of an ideal gas be connected by an isothermal process as well as an adiabatic process?

An ideal gas undergoes a process consisting of adiabatic and isothermal process only as shown in the figure. Then :

In an isothermal process for an ideal gas

An ideal gas is expended adiabatically then

The following P-V graph shows five different thermodynamics process on an ideal gas. The processes numbered '2' and '4' are adiabatic and isothermal respectively. Let W be the work done by the gas, DeltaU be the increment in internal energy, Q be the heat absorbed by the gas and C be the molar capacity of the gas for the processes. math the columns .

Let Q and W denote the amount of heat given to an ideal gas the work done by it in an isothermal process.

The curves A and B in the figure shown P-V graphs for an isothermal and an adiabatic process for an idea gas. The isothermal process is represented by the curve A.

The curves A and B in the figure shown P-V graphs for an isothermal and an adiabatic process for an idea gas. The isothermal process is represented by the curve A.

Total internal energy of an ideal gas remains constant in isothermal process.
