WebMelting point The temperature at which the solid–liquid phase change occurs. Boiling point The temperature at which the liquid–gas phase change occurs. Sublimation The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. Density (g cm−3) WebNov 11, 2024 · Definition of Boiling Point The temperature at which a liquid boils and turns into a gas. The boiling point temperature will be lower if the atmospheric pressure is decreased. For example the boiling point of pure water at standard atmospheric pressure (or sea level) is 100°C (212°F) while at 10,000 feet (3,048m) it is 90.39° C (194.7°F).

"Web* Boiling Point Notes: 1. Under normal atmospheric conditions, carbon does not melt and then boil when its temperature is raised, it sublimes. i.e. when heated, carbon undergoes a phase change directly from solid to gas. The boiling point quoted is when the vapor pressure of graphite vapor above subliming graphite reaches 1 atmosphere. 2. " - Elements boiling and melting points
