MCQ
The gas law $\frac{{PV}}{T} = $ constant is true for
- AIsothermal changes only
- BAdiabatic changes only
- ✓Both isothermal and adiabatic changes
- DNeither isothermal nor adiabatic changes
✓
Answer
Correct option: C.
Both isothermal and adiabatic changes
c
(c) For an ideal gas$:$
(c) For an ideal gas$:$
$P V=n R T$
$\frac{P V}{T}=n R=$ constant
Which is valid for all processes, which includes isothermal or adiabatic.
Hence option $\mathrm{C}$ is correct.
