SpletMolecular solids have low melting (T m) and boiling (T b) points compared to metal (iron), ionic (sodium chloride), and covalent solids (diamond). [4] [5] [8] [13] Examples of molecular solids with low melting and boiling temperatures include argon, water, naphthalene, nicotine, and caffeine (see table below). Splet12. okt. 2024 · Heat Generation Consideration of PC3L RAM Vs PC3. The higher voltage power of PC3 RAM generates high heat than PC3L RAM. Although by doing so, it offers solid as well as faster operating performances. However, there is a chance of overheating your device system. In contrast, the PC3L RAM module generates less heat as it uses …
