← ScienceWhich 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.
