If the pressure of a gas increases by \(2 \%\) at constant volume, then its temperature
- A increases by \(2 \%\)
- B decreases by \(2 \%\)
- C does not change
- D decreases by \(1 \%\)
Answer & Solution
Correct Answer
(A) increases by \(2 \%\)
Step-by-step Solution
Detailed explanation
Using ideal gas equation, \(\mathrm{PV}=\mathrm{nRT}\) Volume is constant, \(\begin{aligned} & \frac{P}{T}=\frac{n R}{V}=\text { constant } \\ & P \propto T\end{aligned}\) If pressure increase by \(2 \%\) than temperature is also increase by \(2 \%\)
