Passage / Comprehension
The adiabatic compression of a mixture of 3 volumes of hydrogen and 1 volume of oxygen from 640 ml to 20 ml caused explosion. The initial pressure and temperature of the gaseous mixture were 2 atm and 127°C.
What is the pressure of the gaseous mixture at the moment of explosion?
Options:
Answer:
C
Solution:
Both gases are diatomic, so γ = 7/5 = 1.4 for the mixture. P₂ = P₁(V₁/V₂)γ = 2 × (640/20)1.4 = 2 × 321.4 = 2 × 2⁷ = 256 atm. Matches (c).
