Principles of Chemistry Flashcards
Conversion of solid to liquid
Melting
How do particles move in a gas?
Move quickly in all directions
How do particles move in a solid?
Vibrate about a fixed point
Conversion of liquid to gas
Evaporation
How do particles move in a liquid?
Move around each other
Conversion of gas to liquid
Condensation
Conversion of gas directly to solid
Sublimation
What conversion occur at the melting point?
Melting and Freezing
What conversions occur at the boiling point?
Evaporation and Condensation
Strong forces between particles =
More energy required to overcome bonds - high boiling point
Solvent
The liquid in which a solute dissolves
Solute
The substance which dissolves in a liquid to form a solution
Solution
The mixture formed when a solute is dissolved in a solvent
Saturated solution
A solution with the maximum concentration of solute
dissolved in the solvent
