Answer:

0.9L

Explanation:

Given parameters:

Initial volume = 2.1L

Initial pressure  = 101kPa

Final pressure  = 235kPa

Unknown:

Final volume  = ?

Solution:

The relationship is between pressure and volume. To solve this problem, we apply Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".

Mathematically;

        P₁V₁  = P₂V₂

P₁ is the initial pressure

V₁ is the initial volume

P₂ is the final pressure

V₂ is the final volume

 Now insert the parameters and solve;

        2.1 x 100 = 235 x V₂

            V₂ = 0.89L

Answer:

D) 0.9 L

Explanation:

At constant temperature,

PV = Constant

so,

P1.V1 = P2. V2

101 × 2.1 = 235 × V2

V2 = 0.9 L
