Answer:
The volume of the second cylinder is 80 liters
Explanation:
We use the Boyle-Mariotte formula, according to which the pressure and volume of a gas are inversely related, keeping the temperature constant: P1 x V1 = P2xV2. We convert the pressure in mmHg to atm:
760 mmHg-----1 atm
380mmHg------x= (380mmHgx1atm)/760mmHg=0,5 atm
P1xV1=P2xV2
2 atmx20 L= 0,5atm x V2 V2=(2 atmx20 L)/0,5atm=80L
