Formula:

Final- Initial = volume

Temperature

• warm - high kinetic energy

• molecules further apart ( Less dense)

• Cold - lower kinetic energy

• Molecules are more compact ( more dense)

Multiple Select

Temperature has which effect on density?

• NO effect

• warm less dense

• cool more dense

Concentration

• high concentration of substance increases density

• low concentration = lighter density
