A gas occupies 11.2 liters at 0.860 atm. What is the pressure if the volume becomes is doubled? * 3 points Doubled Quadrupled Decreased by a factor of 4 Half as much as it was

Half as much as it was

Explanation:

According to Charles law

PV = k

P is the pressure

V is the volume

If PV= k, then P1V1= P2V2

P1 and P2 are the initial and final pressure respectively

V1 and V2 are the initial and final volume respectively

Given

V1 =11.2litres

P1 = 0.860atm

If the volume is doubled, V2 = 2(11.2) = 22.4litres

Get P2

P2 = P1V1/V2

P2 = 0.860×11.2/22.4

P2 = 0.860/2

P2 = P1/2 (since P1 =0.860)

P2 = 1/2 P1

Hence the pressure becomes halved if the volume is doubled
