Which consequence results when the vapor pressure exceeds ambient pressure during isochoric heating of isobutane fuel?

A)Rapid, adiabatic cooling diminishes combustion
B)Sudden boiling causes destructive BLEVE
C)Reversible vapor compression liquefies fuel
D)Viscosity increases and diffusion slows

💡 Explanation

Sudden boiling causes a Boiling Liquid Expanding Vapor Explosion (BLEVE) because isochoric heating increases temperature and therefore vapor pressure rapidly. This exceeds ambient pressure, rather than achieving steady-state evaporation or orderly combustion.
