Question

A certain gas is present in a 10.0 L cylinder at 1. 0 atm pressure it the pressure increased to 2 0 atm the volume of the gas decreases lo 5 0 L Find the two constants k the value 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 If a certain gas occupies a volume or 16 L when the applied pressure a 8 0 atm nod me pressure of 4 0 L Express your answer to two significant figure and include the appropriate unit

Explanation / Answer

C)

ki = Pi x Vi = 1 x 10 = 10

now

kf = Pf x Vf = 2 x 5 = 10

as

ki = kf

the gas obeys boyles law

now

ki x kf = 10 x 10 = 100

D)

we know that

according too Boyles law

P1V1 = P2V2

given

P1 = 8

V1 = 16

V2 = 4

so

8 x 16 = P2 x 4

P2 = 32

so

the pressure is 32 atm when the gas occupies a volume of 4 L
