Melting point and decomposition temperature
Web9 nov. 2014 · The different molar quantities of melamine ranging from 0.1 M to 0.25 M and fixed formaldehyde of 1 M were used at constant temperature of 75°C and pH 8.5. The polymerization reaction was conducted for two hours under constant agitation for obtaining higher degree of conversion. The pH of the reaction mixture was maintained at 8.5 by … WebThe melting point of water is 0°C 32°F; that's the temperature that ice melts into water. If the melting point of a solid is 3°C then that means it will melt from a solid to a liquid at 3°C. Above that temperature the pure substance is a liquid.
