when the pressure on 2.5liters of oxygen is decreased from 2.0atm to 1.0atm,the volume of the gas becomes how many liters.(round answer to one decimal place.

Answer 1

p1v1 = p2v2

Answer 2

1.3

Answer 3

To determine the volume of the gas when the pressure is decreased, you can use Boyle's Law, which states that the pressure and volume of a gas are inversely proportional when temperature is kept constant.

Boyle's Law formula: P₁V₁ = P₂V₂

Where:
P₁ = Initial pressure of the gas (2.0 atm)
V₁ = Initial volume of the gas (2.5 liters)
P₂ = Final pressure of the gas (1.0 atm)
V₂ = Final volume of the gas (unknown)

Rearranging the formula, we get:

V₂ = (P₁V₁) / P₂

Substituting the given values in the formula:

V₂ = (2.0 atm * 2.5 liters) / 1.0 atm

V₂ = 5.0 liters

Therefore, when the pressure on 2.5 liters of oxygen is decreased from 2.0 atm to 1.0 atm, the volume of the gas becomes 5.0 liters.
