Boyle's Law question

Part C A certain gas is present in a 10.0L cylinder at 3.0atm pressure. If the pressure is increased to 6.0atm the volume of the gas decreases to 5.0L . Find the two constants ki, the initial value of k, and kf, the final value of k, to verify whether the gas obeys Boyle's law. Express your answers to two significant figures separated by a comma. Part D If a certain gas occupies a volume of 20L when the applied pressure is 10atm , find the pressure when the gas occupies a volume of 5.0L Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

1.

P1V1= K1= 10*3=30

P2v2= Kf= 5*6=30

since K1=Kf

the gas follows boyles law

2.

P1V1=P2V2

10*20= P2*5

P2= 40 atm
