A Gas is allowed to expand from its original volume 250cm3 at 25C by pressure 2.5x105pa so its volume at 25C becomes 3.50dm3.calculate new pressure in atm?

Explanation:

Since the temperature of the gas is constant , we use Boyle's law formula

P₁ V₁ = P₂ V₂

P₁ = 2.5  x 10⁵ Pa

V₁ = 250 x 10⁻⁶ m³

V₂ = 3.5 x 10⁻³m³

P₂ = ?

Putting the values in the equation

2.5  x 10⁵ x 250 x 10⁻⁶ = 3.5 x 10⁻³ P₂

P₂ = 2.5  x 25 / 3.5 x 10⁻³

= 17.86 x 10³ Pa

= .1786 x 10⁵ Pa

= .1786 x 10⁵ / 1.013 x 10⁵ atm

= .176 atm
