Question

16 A fixed mass of gas has a volume of 25 cm³. The pressure of the gas is 100 kPa. The volume of the gas is slowly decreased by 15 cm³ at constant temperature. What is the change in pressure of the gas?

A 67 kPa
B 150 kPa
C 170 kPa
D 250 kPa​

Answer 1

Step-by-step explanation:

v1 = 25

V2= 15

P1= 100

p2 = x

using Boyle's law

pv =k

p1v1=p2v2

100 X 25/15 = x

x = 166.7 kPa
