A balloon will pop in the atmosphere because..

• Pressure goes down volume goes up
• Pressure goes up volume goes down
• temperature goes down volume goes up
• volume goes down temperature goes down

A gas that has a pressure of 2 atm and a volume of 10 L. What would the new volume be if the pressure was 1 atm. Which formula would you use?

• P1/T1 = P2/T2

• P1V1 = P2V2

• V1/n1 = V2/n2

• PV = nRT
