The gas in a large balloon has a volume of 1.35 liters and a pressure of 1.75 atm. What will the pressure be if the volume is increased to 3.15 liters?

Please show work.

The pressure of a gas is inversely proportional to its volume, so the pressure will decrease when the volume increases. We can use the equation P1V1 = P2V2 to calculate the new pressure.

P1V1 = P2V2
1.75 atm x 1.35 L = P2 x 3.15 L
P2 = 0.848 atm
AAAaannndd the bot gets it wrong yet again!
right numbers, yet still gets the wrong answer!

3.15P = 1.35 * 1.75
P = 0.75 atm
