Chemistry Regents Review: Physical Behavior of Matter & all units (week #7)

Aqueous

dissolved in water

Solubility changes as ________ changes.

temperature

As temperature increases, the solubilty of solid compounds….

increases

As temperature increases, the solubilty of gases…

decreases

Freezing Point Depression

freezing point of a solvent is lowered by adding a solute

Boiling Point Elevation

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

More particles means

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

Vapor Pressure

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

Thermal Energy

total kinetic and potential energy of the particles in an object, which determines its temperature and ability to transfer heat

Entropy

systems go from low energy to greater disorder (chaos)
