Heating graph chemistry
Web19 de jul. de 2024 · A heating curve of a substance shows the relationship of temperature, state of matter, and heat (when added over time). Substances undergo phase transitions at their melting and boiling points. Consider a substance in the solid state below its freezing point. To convert the substance to a gas above the boiling point, the following must occur: WebAlso use the data from a cooling curves practical to complete various graph-drawing exercises. Heating and cooling curves can be drawn at different levels of abstraction: the representative graph of a particular experiment, the universal graph for the substance being analysed, and an even more abstract ‘generic’ curve showing the overall pattern.
