Introductionto Matter

(the amount of _____ )

MATTER

Matter: Is anything that has _____ and _______.mass volume

Is the measure of the ________ of matterMass: quantity

• Units used: g (grams) kg (kilograms)

• Note: There is usually confusion between the term mass and weight….let’s clarify...

atoms a substance contains.

acting on the amount of ____ contained in an object.

MATTER

• Mass depends on the _______________ there are in an object.

Mass Weight• Weight depends on the

_______________

EarthMoon

Since the Moon is 1/6th the size of Earth, it has

1/6th of Earth’s gravitational pull.

This means that objects will weigh 1/6th LESS on

the Moon than on Earth.

mass = 5000 kg mass = 5000 kg

weight = 5000 kg weight = 833 kg

BUT the mass (amount of atoms) will remain

the same.

number of atoms amount of gravitymass

(the amount of _____ )

MATTER

Matter: Is anything that has _____ and _______.mass volume

Is the measure of the ________ of matterMass: quantity

• Units used: g (grams) kg (kilograms)atoms a substance contains.

Is the measure of the _______________ a substance takes up.

Volume:

• Units used: mL (milliliters) L (liters)

amount of space

STATES OF MATTERMatter comes in 3 States:

Solid

Liquid

Gas

3 States

Guess these states of matter.

STATES OF MATTER

definite

indefinite

indefinite indefinite

• small distances• low energy and little movement (vibrations only)

• more distances• more energy and more movement

• large distances• high energy and a lot of movement

definite = unchangeable indefinite = changeable
