Initial volume is 2.3l, initial temperature 150k and initial pressure 15psi. temperature doubles and pressure
is halved. the new volume is what?

V₂ = 9.2 L

Explanation:

Initial volume = 2.3 L

initial temperature = 150 K

Initial pressure = 15 psi

Final temperature = 300 K

Final pressure = 7.5 psi

Final volume = ?

Solution:

P₁V₁/T₁ = P₂V₂/T₂

V₂ = P₁V₁T₂ /T₁ P₂

V₂= 15 psi × 2.3 L × 300 K / 150 K × 7.5 psi

V₂  =10350 psi .L.  K  / 1125 K .psi

V₂ = 9.2 L

where are the choice options?
