Question

Which of the following samples of gas would have a new volume of 4.00 liters if the pressure is decreased from 8.00 atm to 2.00 atm at constant temperature?

Group of answer choices

8.00 L H₂

4.00 L CO₂

2.00 L He

1.00 L N₂

Answer 1

Initial volume (V)=4.00L Initial pressure (P)=2.00 atm Final volume (V2)=? Final pressure(P2) = 8.00 atm At constant temperature, the pressure of gas is inversely proportional to volume of the gas. pa= = PV=Constant = V = 5 x V _2.00 atm x 4.00L 8.00 atm =1.00L Hence, the final volume of the gas is 1.00L N,
