a balloon has a volume of 1.25 L at 1.5 atm of pressure. What is the volume on the baloon and 0.25 atm of pressure?

kvv77 [185]

Answer: 7.5 L

Explanation: According to Boyle's law, V1P1=V2P2. This means that

(1.25)(1.5)=(V2)(.25), so 1.875/.25=V2, so the volume of the baloon at .25 atm is equal to 7.5 L.
