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. |
