Nov 30, 2022 · 1 What is the difference between "smell/odor" and "vapor" of a substance? It is assumed that the vapor of a given compound/element is the gas phase of the same pure compound/element. …
Question about vapor pressure in solids and liquids
Jun 14, 2023 · I've been reading about vapor pressure and it's a bit confusing. For example when water is in equilibrium between the solid and liquid phase, my textbook says that the vapor pressure is …
equilibrium - Why doesn't the vapour pressure exceed the external ...
Aug 29, 2024 · A closed container is a pressure cooker. Pressure increases, though active boiling ceases when the increased pressure of the vapor above the liquid prevents bubbles from forming. …
