Answer:

V2= 625 cm^3

Explanation:

P1 × V1 = P2 × V2

P1 (initial pressure)=125 kPa

V1 ( initial volume)= 450 cm^3

P2 (final pressure)=90kPa

V2 (final volume)= ?

Rearrange the equation to make V2 the subject, since it is the value we are trying to find

V2=(P1 × V1)/P2

V2= (125 ×450)/90

V2= 625 cm^3
