WebThe Tipping Point: How Little Things Can Make a Big Difference is the debut book by Malcolm Gladwell, first published by Little, Brown in 2000. Gladwell defines a tipping point as "the moment of critical mass, the threshold, the boiling point." [1] The book seeks to explain and describe the "mysterious" sociological changes that mark everyday life. WebWhen table salt is added to water the resulting solution has a higher boiling point than the water did by itself. The ions form an attraction with the solvent particles that then prevent the water molecules from going into the gas phase. Therefore, the salt-water solution will not boil at 100 o C.
WebApr 14, 2024 · This chemistry video tutorial provides a basic introduction into colligative properties such as boiling point elevation, freezing point depression, osmotic pressure, and vapor pressure. It... WebMar 5, 2024 · Boiling commences when the vapor pressure of a liquid or solution equals the external or applied pressure (often the atmospheric pressure). Thus, if the applied pressure is reduced, the boiling point of the liquid decreases. This behavior occurs because a lower vapor pressure is necessary for boiling, which can be achieved at a lower temperature.
