Question

The pressure P of a gas varies inversely with its volume, V. Pressure is measured in units of Pa. Suppose that A particular amount of a gas is initially at a pressure of 104 Pa at a volume of 108 L. If the volume is expanded to 432 L , what will the new pressure be ?

Answer 1

p = k/v
or
p v = k
so
P2 V2 = P1 V1

P2 = (V1/V2) P1

P2 = (108/432)(104)

Answer 2

so tis 26 Pa
yw :]
