CHAPTER 2
MATTER AND CHANGE
(Part 1)
Matter, Mass, and Volume
Matter
def: anything that has mass and takes up space.
Volume = space matter occupies.
Volume
def: Amount of space that a substance or an object takes up.
Can be measured 2 ways:
Regular Shaped Objects
Calculating from measurements
Length x Width x Height
Irregular Shaped Objects
Water Displacement
Dropping an object into water and observing how the water level changes.
Mass
def: Measured amount of matter in a substance or object.
Measured using a balance/scale
Mass vs. Weight
Mass - amount of matter an object or substance (kg)
Weight - amount of matter of an object PLUS the force of gravity acting on the object (pounds)
Matter is all the “stuff” that exists in the universe. It has both mass and volume.
Mass measures the amount of matter in a substance or an object. The basic SI unit for mass is the kilogram (kg).
Volume measures the amount of space that a substance or an object takes up. The basic SI unit for volume is the cubic meter (m3).
Pure Substance
def: Matter that has a uniform and definite composition
In other words: Matter that is the same throughout the sample.
One of the characteristics of a substance is that it cannot be separated into components by physical separation techniques.
Element:
C - Carbon
He - Helium
K - Potassium
def: the simplest form of matter that has a unique set of properties
118 different known elements
Compound
Water - H2O
Carbon Dioxide - CO2
def: substance that contains two or more elements chemically combined in a fixed proportion.
Can be a Liquid
Can be a Gas
Can be a Solid
