How melting is different from freezing
Under a standard set of conditions, the melting point of a substance is a characteristic property. The melting point is often equal to the freezing point. However, under carefully created conditions, supercooling, or superheating past the melting or freezing point can occur. Water on a very clean glass surface will often supercool several degrees below the freezing point without freezing. Fine emulsions of pure water have been cooled to −38 °C without nucleation to form ice. Nucleation o… WebAccording to the Van´t Hoff equation, the relation between free energy, Δ G, and K is Δ G° = - RT ln K, where R is the ideal gas law constant, and T is the kelvin temperature of the reaction. This gives, for the nucleic acid system, . The melting temperature, Tm, occurs when half of the double-stranded nucleic acid has dissociated.
