the temperature does not change. hence we do so on the basis of the Boyle Marriott law.
Boyle Marriott's law: the pressure of a gas at constant temperature is inversely proportional to its volume. that is,
P1 / P2 = V 2/ V1
where, P1 —is the initial pressure, P2 —is the next pressure, V1 —is the initial volume, and V2—is the next volume
according to the circumstances of the case
P2=1.5*104 Pa = 15*103 Pa
V2=P1*V1/P2= 5.6*103* 1.53/15*103= 0.5712 L or 571.2 ml
ANSWER: 0.5712 L or 571.2ml
