Q: The vapor pressures of various liquids depends primarily on the strength of what kind of attractions between individual particles?


Read this paragraph and choose the correct option from the provided answers:

As we saw when we studied States of Matter , the driving force for particles in the liquid phase to escape into the gas phase depends on both the temperature and identity of the substance. The vapor pressure of a liquid is a measure of this ability. Specifically, vapor pressure is the pressure exerted by a vapor that is in equilibrium with its solid or liquid phase. For substances with a stronger drive to enter the gas phase, more vapor particles will be present in the same amount of space, resulting in a higher pressure. At a given temperature, the vapor pressures of various liquids depends primarily on the strength of intermolecular attractions between individual particles. Figure below shows the relative vapor pressures of several different substances.

 Choices:

- diffusion

- gravitational

- outer molecular

- intermolecular


A:
intermolecular
