A \(0.20\) mol sample of an ideal gas occupies a \(5.0\) L rigid container at \(20^{\circ}\text{C}\) and a pressure of \(100\ \text{kPa}\). The gas is heated at constant pressure until its temperature reaches \(80^{\circ}\text{C}\). It is then compressed adiabatically back to its original volume. Assuming the gas is diatomic with \(\gamma = 1.4\), calculate the final pressure of the gas in kPa (to three significant figures).

Answer Options

A. 115 kPa
B. 145 kPa
Correct Answer C. 130 kPa
D. 160 kPa
Correct Answer
C
Correct Option:
130 kPa
