Highest to lowest melting point

Web13 de abr. de 2024 · The melting rate is also seen highest at the beginning of the simulation and then continuously decreases. The highest and lowest values of the melting rate are 5 and 0.52 g/s, respectively, and their ratio is about 9.6 times. This value is slightly less than the ratio of the temperature drop's highest-to-lowest rate, which is about 10.9. For most substances, melting and freezing points are approximately equal. For example, the melting point and freezing point of mercury is 234.32 kelvins (−38.83 °C; −37.89 °F). However, certain substances possess differing solid-liquid transition temperatures. For example, agar melts at 85 °C (185 °F; 358 K) and solidifies from 31 °C (88 °F; 304 K); such direction dependence is known as hy…
