Question

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

✓

Answer

No,
In a system either temperature varies or it heat varies.
In case of ideal gas Internal energy is function of temperature only thus for isothermal process change in internal energy is zero.
Now, since process is adiabatic thus heat exchange is zero.
therefore, work done is also zero.
