Answer 2

Answer:

The volume of the oxygen gas will become 364.5cm³.

Explanation:

From the Boyle's law , we know that pressure is inversely proportional to volume.i.e.

$P\propto\frac{1}{V}$    (1)

Where,

P=pressure applied

V=volume of the gas=r³          

Equation (1) can also be written as,

$P_1V_1=P_1V_2$       (2)

From the question we have,

P₁=P

P₂=2P

r₁=9cm

By substituting the values in equation (2) we get;

$P\times (9)^3 =2P\times V_2$

$V_2=\frac{729}{2}=364.5cm^3$

Hence, the volume of the oxygen gas will become 364.5cm³.
