What 4 things does the kinetic molecular theory state?
all matter is made up of small particles
the particles have KE which causes them to constantly move
particles have greater KE at higher temperature
collisions of particles does not result in a loss of KE
What is the particle composition of solids?
held in a fixed position
can vibrate in position
What is the particle composition of liquids?
particles are more spread out but still attracted to each other
What is the particle composition of gasses?
particles are very spread out
move in random straight lines
What is the equation for density?
density = mass/volume
what is sublimation?
solid to gas
why does temperature not increase from point 2-3?
Added heat is being used to over intermolecular forces
What are the endothermic states of changes?
sublimation, evaporation and melting
What are the exothermic states of changes?
deposition, condensation and freezing
