A scuba diver begins to surface carrying a tank containing 4.0 L of a gas at 730 mm Hg. What volume will the gas occupy at 760 mm Hg?

O A. 3.8 L

OB. 4.2 L

O C. 120 mm Hg

O D. 920 mm Hg

3.8 L

Explanation:

From Boyle's law;

P1 V1 = P2 V2

P1 = initial pressure = 730 mm Hg

P2 = final pressure = 760 mm Hg

V1= Initial volume = 4.0 L

V2 = final volume = ?

V2 = P1 V1/P2

V2 = 730 × 4/760

V2 = 3.8 L

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
