Answer to Question #334149 in Chemistry for shimmy

Question

1. Oxygen gas inside a 1200 litres gas tank has a pressure of 1.0 atm. If the temperature remains constant , how much pressure is needed to reduce its volume by one- half (1/2) ?

Answer 1

P₁ = 1.0 atm

V₁ = 1200 L

T₁ = T₂ = constant

P₂ = ???

V₂ = (1/2) × V₁ = (1/2) × 1200 L = 600 L

Solution:

Since the temperature and amount of gas remain unchanged, Boyle's law can be used.

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

To find the pressure, solve the equation for P₂:

P₂ = P₁V₁ / V₂

P₂ = (1.0 atm × 1200 L) / (600 L) = 2.0 atm

P₂ = 2.0 atm

Answer: 2.0 atm
