Solution

The correct option is B both isothermal and adiabatic changes
For an ideal gas:
$P V = n R T$
$\frac{P V}{T} = n R = c o n s t a n t$
Which is valid for all processes, which includes isothermal or adiabatic.
Hence option C is correct.

Q. The temperature at which adiabatic change is equivalent to the isothermal change ?

Q. Assertion :In a gas any rapid change must be adiabatic whereas a slow change may be adiabatic. Reason: In a P-V diagram, the magnitude of the slope is greater for an adiabatic process than for an isothermal process.
