Explanation / Answer

part C )

Let us assume the gas obeys Boyles. law

Then PV = constant

At state 1 P1 = 1.0 atm and V1= 10L

then P2 = 2.0 atm and V 2= 5.0L

Thus

ki = P1V1 = 1.0atm x 10.0L = 10 and

kf = P2V2 = 2.0 atm x 5.0L = 10

Thus Ki = Kf = 10 and thus the gas obeys BoYe's law

Part D

P1 = 9.5 atm P2 = ?

V1 = 19L V2 = 4.8 L

According to Boyle's law

P1V1 = P2V2

9.5 atm x19 L = 4.8L xP2

Thus P2 = 37.60 atm
