PROPERTIES OF MATTER

MASS

• large body of matter with no definite shape
• Mass can be measured with balance or scale
• M=F/A (m=mass, F=force, A=acceleration)
• Metric units of mass are kilograms and grams
• Temperature can change mass

WEIGHT

• a body's relative mass; the heaviness of a person or things
• Can be measured with a scale
• W=mg (W= weight, m=mass, g= gravitational acceleration)
• grams, kilograms, milligrams
• Age and size can change weight

VOLUME

• the amount of space that a substance or object occupies
• You can measure volume w/ measuring cups & graduated cylinder
• V= lwh (length, width, height)
• Metric units of volume are liters and milliliters
• Size can change the volume of an object

DENSITY

• The degree of compactness of a substance
• You can measure density with a hydrometer
• D=m/v (mass/volume)
• Grams and centimeters are used to measure density
• Temperature and pressure can change density
