Question

20.0L of has at 844 kPa of pressure expands to 40.0L. What is the new pressure of the gas

Answer 1

Answer:

P₂ = 422 kPa

Explanation:

Given data:

Initial Volume of gas = 20.0 L

Initial Pressure of gas = 844 kPa

Final volume = 40.0 L

Final pressure = ?

Formula:

According to Boyle's Law

P₁V₁ = P₂V₂

Solution:

P₁V₁ = P₂V₂

P₂ = P₁V₁ /V₂

P₂ = 844 kPa × 20.0 L / 40.0 L

P₂ = 16880 kPa. L /40.0 L

P₂ = 422 kPa
