Density

 Which is heavier- a pound of lead or a pound of feathers?  Most people will answer lead, but the weight is exactly the same  They are normally thinking about equal volumes of the two  The relationship here between mass and volume is called Density

Density  The formula for density is: mass volume Common units are: g/mL, or possibly g/cm 3, (or g/L for gas) Density is a physical property, and does not depend upon sample size Density =

- Page 90 Note temperature and density units

Density and Temperature  What happens to the density as the temperature of an object increases?  Mass remains the same  Most substances increase in volume as temperature increases  Thus, density generally decreases as the temperature increases

Density and Water  Water is an important exception to the previous statement.  Over certain temperatures, the volume of water increases as the temperature decreases (Do you want your water pipes to freeze in the winter?)  Does ice float in liquid water?  Why?
