Term Definition
physical changes melting, freezing, vaporization, condensation, sublimation
physical identity doesn't change
Melting point temperature at which a substance changes from a solid to a liquid (vary between sustances)
Melting Solid to a liquid+endothermic change
Freezing point temperature at which a substance changes from a liquid tp a solid
Freezing liquid to a solid+Exothermic change
Vaporization liquid to a gas+endothermic
Boiling occurs throughout a liquid
Boiling point temp. at which a liquid boils
Evaporation occurs only at the surface of a liquid below its boiling point
Condensation gas to liquid+ exothermic change
Condensation Point at sea level occurs at same temp. as boiling point -100
Sublimation solid to gas+ Endothermic ex: dry ice
Endothermic adding energy
Exothermic taking away energy
Boyls Law Deals with constant temperature – if the pressure is decreased, the volume will increase.Is the relationship between pressure and volume
Charles Law Deals with constant pressure – if the temperature decreases, the volume will decrease. Also, if the temperature increases the volume will increase. Examples include our balloon lab, a basketball getting flat in the winter, a bike tire getting flat in the winter
Melting and Freezing Point occur at the same temperature – It just depends whether energy is added or removed at that point
Plasma aurora borealis fire lightining?
