freezing point of a solvent is lowered by adding a solute

New cards
6

Boiling Point Elevation

increase in the boiling point of a solvent due to the presence of a solute dissolved in it

New cards
7

More particles means

higher boiling point and lower freezing point b/c harder to remove and break IMF attraction

New cards
8

Vapor Pressure

a measure of the tendency of a material to change into the gaseous or vapour state

New cards
