When the pressure changes from 1417 psi to 160.186 psi the volume changes from 0.145 L to 0.878 l and the temperature changes from 287 k to 196 k

Explanation:

According to general gas equation:

P₁V₁/T₁ = P₂V₂/T₂

Given dа ta:

Initial volume = 0.145 L

Initial pressure = 1417 psi (1417/14.696 = 96.42 atm)

Initial temperature = 287 K

Final temperature = 196 K

Final volume = 0.878 L

Final pressure = ?

Formula:

P₁V₁/T₁ = P₂V₂/T₂

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

Solution:

P₂ = P₁V₁ T₂ / T₁ V₂

P₂ = 96.42 atm * 0.145 L * 196 K / 287 K * 0.878 L

P₂ = 2740.26 atm. L. K / 251.99 k. L

P₂ = 10.9 atm

atm to psi:

10.9 * 14.696 = 160.186 psi
