A bicycle tyre is filled with air having pressure of \(270\,kPa\) at \(27^{\circ}\,C\). The approximate pressure of the air in the tyre when the temperature increases to \(36^{\circ}\,C\) is \(............kPa\)
- A \(270\)
- B \(262\)
- C \(278\)
- D \(360\)
Answer & Solution
Correct Answer
(C) \(278\)
Step-by-step Solution
Detailed explanation
Taking volume constant:\(\frac{ P _1}{ T _1}=\frac{ P _2}{ T _2}\) \(\Rightarrow P _2=\frac{ P _1}{ T _1} \times T _2=\frac{270 \times(309)}{300}\) \(=278\,kPa\)
