SUMMARY
The final pressure of a compressed and cooled ideal gas can be calculated using the equation P1 V1 / T1 = P2 V2 / T2. Given the initial conditions P1 = 90.0 kPa, V1 = 0.0800 m³, T1 = 300 K, V2 = 0.0400 m³, and T2 = 260 K, the correct calculation yields P2 = 135.0 kPa. The initial attempt at solving this problem incorrectly used extraneous values and units, leading to an incorrect pressure result of 0.67 atm.
