← ScienceWhich outcome occurs when a closed steel tank containing liquid ammonia is heated above its critical temperature?
A)Complete vaporization with uniform density✓
B)Stratification into distinct liquid/gas phases
C)Pressure decrease due to dissociation
D)Solidification due to increased intermolecular forces
💡 Explanation
When a liquid is heated above its critical temperature, the distinction between liquid and gas phases vanishes because the meniscus disappears due to identical densities, producing a homogenous supercritical fluid. Therefore complete vaporization results, rather than stratification because two-phase equilibrium can not be maintained at supercritical conditions, or dissociation/solidification which require distinctly different conditions.
