Answer :
Boyle's law states that "the volume V and pressure P of a given quantity of gas is inversely proportional to each other if the temperature remains constant".
Boyle's law is expressed as;
P₁V₁ = P₂V₂
Given data:
Initial Volume V₁ = 2.5L
Initial pressure P₁ = 6.0atm
Final pressure P₂ = 7.5atm
Final volume V₂ = ?
We will substitute the values in the above expression to determine the final volume of the gas.
P₁V₁ = P₂V₂
V₂ = P₁V₁ / P₂
V₂ = ( 6.0 × 2.5 ) / 7.5
V₂ = 15 / 7.5
V₂ = 2.0L
Hence, the volume of the gas decreases to 2.0L.
