science studying
Crystalline- Cr(ys)talline | melts at specific tempurature |
Amorphous- A(mo)rphous | does not melt at specific tempurature |
surface tension | inward pull of molecules on the surface of a liquid that pulls them together. |
viscosity | liquid's resistance to flow |
fluids- (flu)ids | substances that flow |
melting | solid to liquid |
melting point | temp. at which a solid melts |
freezing | liquid to solid |
freezing point | temp. at which liquid freezes |
vaporation | liquid to gas |
boiling point | temp. at which boiling occurs |
condensation | gas to liquid |
sublimation | solid to gas |
desublimation | gas to solid |
pressure | force/area |
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. |
