Solve for p2. p1v1 = p2v2

lukranit [14]

Answer:

P₂ = $\frac{P_{1} V_{1} }{V_{2} }$

Step-by-step explanation:

Given expression:

Boyle's law:

P₁ V₁ = P₂ V₂

Problem is to find P₂;

Solution:

P₁ V₁ = P₂ V₂

To solve this problem, multiply both sides by $\frac{1}{V_{2} }$ ;

P₁ V₁ x $\frac{1}{V_{2} }$ ; = P₂ V₂ x $\frac{1}{V_{2} }$ ;

$\frac{1}{V_{2} }$ cancels out V₂ on the right hand side;

P₂ = $\frac{P_{1} V_{1} }{V_{2} }$

Hey!

We know that d = 2r
where,
r - radius
d - diameter
Since it is given that d = 8 inches = 20.32 cm
Therefore,
radius ( r ) = d/2
= 8/2
= 4 inches = 10.16 cm //
