A sample of gas has an initial volume of 23.6 l at a pressure of 1.52 atm . if the sample is compressed to a volume of 10.5 l: ,
nataly862011 [7]

New pressure=3.42 atm

Explanation:

using Boyle's law

P1 V1= P2 V2

P1= initial pressure

V1= initial volume

P2= final pressure

V2=final volume

23.6 (1.52)=P2 (10.5)

P2=3.42 atm

so final pressure= 3.42 atm
