Boyle's law ViP Boyle V and P have opposite relationships (constant T)
PT law PT burn 'em P and T have the same relationship. constant V does not change
Charle's law Charles watches direct TV. direct relationship between T and V. constant P
does the temperature change during melting? yes
is energy required for each phase change? yes
can both liquid water and steam exist at 100 C? yes
what must be changed, temperature or heat enerqy, during condensation? heat energy
describe the arrangement of particles as heat energy and temperature increase. spread out
what rule can you state about the relationship between phase changes and temperature? as the phases change, temperature stays the same.
