What is the relationship between the intermolecular forces in a liquid and its vapor pressure?
Vapor pressure is a property of a liquid based on the strength of its intermolecular forces. A liquid with weak intermolecular forces evaporates more easily and has a high vapor pressure. A liquid with stronger intermolecular forces does not evaporate easily and thus has a lower vapor pressure.Click to see full answer. Keeping this in…
Vapor pressure is a property of a liquid based on the strength of its intermolecular forces. A liquid with weak intermolecular forces evaporates more easily and has a high vapor pressure. A liquid with stronger intermolecular forces does not evaporate easily and thus has a lower vapor pressure.Click to see full answer. Keeping this in view, how is the vapor pressure of a liquid related to intermolecular forces?The stronger the intermolecular forces, the stronger the interactions that hold the substance together, the lower the vapor pressure of a liquid at the given temperature, and the harder it is to vaporize a substance.Beside above, what properties indicate strong intermolecular forces in a liquid? Melting Point – The temperature at which a solid turns into a liquid. High melting points indicate STRONG intermolecular forces. Molecules are difficult to separate. Low melting points indicate WEAK intermolecular forces. Likewise, which of the following affects the vapor pressure of a liquid? Vapor pressure is the pressure caused by the evaporation of liquids. Three common factors that influence vapor press are surface area, intermolecular forces and temperature. The vapor pressure of a molecule differs at different temperatures.Why do strong intermolecular forces have lower vapor pressure?Substances with strong intermolecular forces will have lower vapor pressure, because fewer molecules will have enough kinetic energy to escape at a given temperature. Substances with high vapor pressures are said to be volatile – that is, they easily evaporate.
