WebSep 7, 2024 · Why pressure affects boiling point? Pressure affects the boiling point of a liquid because it causes the pressure to increase within the liquid. The higher the pressure, the higher the temperature at which water will start to boil. This is because when water reaches its boiling point, the vapor pressure of water is equal to atmospheric pressure.

The influence of each of these attractive forces will ... WebThe lower the pressure of a gas above a liquid, the lower the temperature at which the liquid will boil. As a liquid is heated, its vapor pressure increases until the vapor pressure equals the pressure of the gas above it. Bubbles of vaporized liquid (i.e., gas) form within the bulk liquid and then rise to the surface where they burst and ...

WebFeb 20, 2016 · When a liquid evaporates in the open, the condensation rate is negligible. Increasing the surface area increases the evaporation rate, but it has little effect on the condensation rate. Hence, water in an open dish evaporates faster than water in a test tube, but the vapour pressure does not change. Answer link

WebApr 9, 2024 · As the branching is done in a molecule or the branches increase the surface area of the molecule decreases which results in the decrease of van der waals attraction. Due to decrease in attraction it becomes easier to overcome a molecule, at low temperature we can overcome it, hence the boiling point of an alkane decreases on branching. how many amps is a megawattWebJul 7, 2024 · What effect does branching of alkane have on boiling point? As branches increases, the surface area of molecule decreases resulting in a small area of contact.
