DENSITY DENSITY = MASS (REFERENCE TABLE) VOLUME Size and shape of the material- . An object made of the same uniform material- A B Mass = 24 grams Mass = 12 grams Volume = 8 cm3 Volume = 4 cm3 Density = grams = Density = grams = cm3 cm3

GRAPH OF DENSITY DENSITY grams/cm3 MASS grams VOLUME cm3 No matter where you are on the density line-

In general – to determine the density of the line. Object A – (greatest density) Object B – Object C – Object D - (least density) FLOATATION - of objects is described in terms of density. Objects that have a greater- Objects that have less- Objects that have the same-

PHASES OF MATTER are described in terms of - In general objects made of the same material will sink (greatest density) and will float (least density). FACTORS THAT AFFECT DENSITY Solid – temperature pressure dense Vapor - temperature

This can be expressed in terms - . density - temperature - density - pressure

WATER Water is the exception to the general rule of density. ***** Water has its maximum density in the ‘Celsius At 3.98 degrees Celsius, the density of liquid water is equal to (see reference table). - Celsius - density density temperature

Temperature (Celsius) TEMPERATURE SCALE – (see reference table) Ice melts/ -at- degrees Fahrenheit degrees Celsius degrees Kelvin Water evaporates/ -at- -density -density - density Solid liquid vapor Temperature (Celsius) 0 degrees - degrees greater than 3.98 degrees
