Answer to Question #111416 in Chemistry for Nya T Johnson

Question

A balloon is filled with 10 L of air at a pressure of 5 atm. What is the pressure of the balloon if the volume is changed to 20 L?

Answer 1

P₁ = 5 atm;

V₁ = 10 L;

P₂ = unknown;

V₂ = 20 L.

Solution:

Since the temperature doesn't change, Boyle's law can be used.

Boyle's gas law can be expressed as: P₁V₁ = P₂V₂.

To find the final pressure, solve the equation for P₂:

P₂ = P₁V₁ / V₂;

P₂ = (5 atm * 10 L) / (20 L) = 2.5 atm.

P₂ = 2.5 atm

Answer: The pressure of the balloon will be 2.5 atm.
