Question

A gas cylinder initially contains 463 L of gas at a pressure of 159 atm. If the final volume of gas is 817 L, what is the final pressure?

Answer 1

The final pressure is 90.1 atm.

Step-by-step explanation:

Assuming constant temperature, we can solve this problem by using Boyle's Law, which states:

• P₁V₁=P₂V₂

Where in this case:

• P₁ = 159 atm

• V₁ = 463 L

• P₂ = ?

• V₂ = 817 L

We input the given data:

• 159 atm * 463 L = P₂ * 817 L

And solve for P₂:

• P₂ = 90.1 atm

The final pressure is 90.1 atm.
