Question

A substance with a higher boiling point will exhibit a:

a.higher vapor pressure
b.lower vapor pressure
c.higher density
d.lower density

Answer 1

A substance with a higher boiling point has stronger intermolecular forces that must be overcome to transition into a gas, resulting in b . a lower vapor pressure at a given temperature.

Step-by-step explanation:

A substance with a higher boiling point will exhibit a lower vapor pressure. This is due to the fact that higher boiling points are indicative of stronger intermolecular interactions within the substance, which require more energy to overcome when transitioning from a liquid to a gas phase. Therefore, at any given temperature, the substance with the higher boiling point will have a lower vapor pressure compared to a substance with a lower boiling point, as it's less prone to evaporation.
