The adiabatic compression of a mixture of 2 volumes of Hydrogen and 1 volume of oxygen from 320 ml to 10 ml caused explosion. The initial pressure and temperature of the gaseous mixture were 1 atm and 27°C.
What is the pressure of the gaseous mixture at the moment of explosion?
Options:
Answer:
B
Solution:
H₂ and O₂ are both diatomic, so the mixture has γ = 7/5 = 1.4. Adiabatic: P₂ = P₁(V₁/V₂)γ = 1 × (320/10)1.4 = 321.4 = (2⁵)1.4 = 2⁷ = 128 atm. Matches (b).
