← ScienceWhich outcome results when a material undergoing solid-liquid phase transition experiences increased pressure?
A)Melting temperature generally increases✓
B)Sublimation rate will sharply increase
C)Crystallization kinetics become extremely slow
D)Triple point becomes thermodynamically stable
💡 Explanation
An increase in pressure on a solid-liquid system shifts the equilibrium via Le Chatelier's principle, favouring the denser phase; because solids are usually, though not always, denser, melting point increases as pressure increases; therefore melting temperature rises, rather than other phase changes which involve gas.
