MEASURING MATTER

MASS MASS is the amount of matter in an object Metric Unit = grams (g), kilograms (kg), or milligrams (mg) Measured on a balance or scale The more matter that is in an object, the more mass it has.

MASS vs WEIGHT WEIGHT refers to the force that gravity exerts on a MASS (the pull of gravity). Think about riding in a roller coaster or on an elevator going up or down… Does your mass change? NO Then why does it feel like your weight changes? The roller coaster/elevator changes the way your body is being pulled down.

VOLUME VOLUME is the amount of space a substance takes up. Metric unit = Liters (L), milliliters (mL), or cubic centimeters (cm3) Measured by: mathematical equation Graduated cylinder water displacement

DENSITY DENSITY is a measure of how closely packed the atoms are in a substance higher density = closer particles lower density = more space between particles Density will change as a substance is heated or cooled

CALCULATING DENSITY DENSITY = MASS ÷ VOLUME 53 mL of water has a mass of 53 g. What is the density of the water? d = m/v d = 53g/53mL d = 1 g/mL A 21 g metal block has a volume of 3 cm3. What is its density? d = 21g/3cm3 d = 7 g/cm3

SINKING & FLOATING DENSITY determines whether an object will SINK or FLOAT If the object is MORE DENSE than the fluid it is in, it will SINK If the object is LESS DENSE than the fluid it is in, it will FLOAT

IDENTIFYING UNKNOWN SUBSTANCES Density is independent of sample size Each substance has a characteristic density no matter how much of the substance you have. The density of an unknown sample can be compared to known densities to identify the sample
