Straight line path, random constant motion,elastic collisions,very small, insignificant volume.
What are the major point of the Kinetic Molecular Theory?
The higher the temp. the more the kinetic energy and pressure it has. less volume=more kinetic energy, volume also increases.
How does a change in temp. affect the kinetic energy, the pressure, and volume of gas molecules.
solids have the strongest IMF's, Gases have the weakest.
Compare intermolecular forces between a solid, liquid, and gas.
Ionic compounds have higher melting points.
Compare the boiling points of Ionic and Covalent compounds.
Freezing point is depressed when adding substance, boiling point is raised when adding substance.
What is freezing point depression, boiling point elevation?
Melting=endothermic, Vaporization=endothermic, Sublimation=endothermic,Deposition=exothermic,Freezing=exothermic,Condensation=exothermic.
what phases of the water cycle are endothermic? exothermic?
High specific heat takes longer to heat up, low specific heat cools down the fastest
What is the difference between high & low specific heat?
Melting is occuring. attractive forces are being overcome.
What is happening at #2 in the time vs. temperature graph?
The air gets hot causing the volume to increase and the pressure to decrease.
What happens to the air inside the tires on a car on a hot day?
Increase=increase in size, decrease=decrease in size.
What happens to the volume of a balloon if the temp. of the air is increased? decreased?
Big container=low, Small container=high.
Is the pressure low or high in a big container? in a small container?
