calculate the final pressure of a gas that is expanded from 725cm³ at 30C and 1.19 atm to 1.12cm³ at 43C​

Final pressure, P2 = 1088.89 atm

Explanation:

Given the following data;

Initial volume, V1 = 725 cm³

Initial temperature, T1 = 30°C

Initial pressure, P1 = 1.19 atm

Final volume, V2 = 1.12 cm³

Final temperature, T2 = 43°C

To find the final pressure (P2), we would use the combined gas law.

Mathematically, the combined gas law is given by the formula;

Substituting into the formula, we have;

Cross-multiplying, we have;

Final pressure, P2 = 1088.89 atm
