Substitute the value of p to the equation.
[tex]p=\dfrac{1}{2},\ p=\dfrac{8}{V}\\\\\dfrac{8}{V}=\dfrac{1}{2}\ \ \ \ |cross\ multiply\\\\(1)(V)=(8)(2)\\\\\boxed{V=16}[/tex]
Given that,
p = 8/V, p = 1/2
Now we can substitute,
The value of p to the equation,
8/V = 1/2
Then use cross multiplication,
→ 1 × V = 8 × 2
→ V = 16/1
→ V = 16
Hence, the value of V is 16.
