Question

The pressure on 30mL of a gas at constant temperature Is changed from 4 atm to 2 atm. What Is the new volume of a gas?

Answer 1

At constant pressure, and constant amount of gas, `Pprop1/V or PV = k`, Boyle's law.

Explanation:

Since `PV = k`, under these condtions, `P_1V_1 = P_2V_2`, so `V_2=(P_1V_1)/(P_2)`; here `(30*mLxx4*cancel(atm))/(2*cancel(atm))` `=` `?? mL`
