Answer:
We have from the Ideal Gas Equation: PV = nRT
Since It is taken into consideration that the mass as well as the Temperature is constant.
It can be written as PV = k(Some constant)
Given chnage in volume = 10 %
New volume =V−0.1V
=0.9V
The pressure for the corresponding volume P
1
is
P
1
×0.9V=k
P
1
=
0.9V
k
Change in pressure =P
1
−P
=
9V
k
The percentage change is =
k/V
k/9V
×100=
9
100
= 11.1 %
