Does acidic lava have a low melting point
WebThe melting point of francium will be around 23-27°C. This is because francium is below caesium in the periodic table, so it should have a lower melting point, and the difference in melting point ... WebMelting point principle: as the molecular weight increases, the melting point increases. This observed in the series lauric (C12), palmitic (C16), stearic (C18). Room temperature is 25 o C, Lauric acid which melts at 44 o is still a solid, while arachidonic acid has long since melted at -50 o , so it is a liquid at room temperature.

WebMelting points. The amino acids are crystalline solids with surprisingly high melting points. It is difficult to pin the melting points down exactly because the amino acids tend to decompose before they melt. Decomposition and melting tend to be in the 200 - 300°C range. For the size of the molecules, this is very high.
