Matter and Its 3 States
Measuring mass and volume
Volume
volume is the amount of space occupied by an object or a body
The bigger the object, the larger the volume
Different units used to measure objects (maths)
litres
cubic centimeter
millilitres
cubic meters
Objects take up space
Object displaces another object
Displace -- > it takes over the space
Measuring Equipment
Measuring cylinders
Beaker
Used to find volume of
Solids
Liquids
Syringes
Volume Liquids
Mass
How to measure mass
Beam balance
the mass of an object can be measured by balancing it with a fixed masses
Can also be used to compare the masses of different objects
Electronic balance
Steps
1 - find the mass of the container
2 - Find the mass of the container and object
3 - Mass of the object = step 2 - step 1
Units
Kg
G
Mass is the amount of matter in an object or a body
Air is matter
Not all matter are visible
Air is matter that we cannot see
Oxygen
Water Vapour
Carbon Dioxide
How to show that air has mass
use two similar inflated balloons
If one balloon is deflated, the other balloon moves downwards
How to show that air occupies space
Push an inverted glass into a basin of water
only a small amount of water will enter the glass
Most of the space in the glass is taken up by air, so water cannot enter the glass completely
Pouring water out of a can with a small hole
1 small hole
water flows out slower
Less air will enter the bottle and less space will be taken up
2 small holes
liquid flows out quickly
When the air flows out of the can from 1 hole air can enter through the other hole to replace the liquid in the can. The air entering through the other hole can also help push the liquid out quickly.
1 big hole
liquid flows out quickly
When liquid flows out of the can through part of the big hole, there is room for surrounding air to enter the can through the same hole to replace the liquid. The air entering the can also help push the liquid out quickly.
Pouring water into a flask with a glass tube/funnel
Introduction to matter
All living and nonliving things are made of matter
Living things
Plants
Fungi
Animals
Microorganisms
Non - Living things
Air
Metals
Non - metals
Glass
Water
Matter is anything that takes up space and has mass
Not matter
Does not
occupy space
have mass
Three states of matter and their properties
States
Liquid
Shape
No definite shape
takes the shape of the container that holds it
When water is transferred from
a beaker to a flask
the water will take the shape of the flask
Volume/Space
Definite
When 100 ml of water in a measuring cylinder is transferred to a beaker
The volume of water in the beaker still remains 100 ml
But shape has changed
Can be compressed?
No
Gas
Shape
No definite shape
takes the shape of the container that holds it
When the cardboard is removed
Brown gas changes it shape to fill flask below
Volume/Space
No definite Volume
occupies the whole container that holds it
after the cardboard is removed
the brown gas changes from
20cm3 to 40cm3
1 more item...
Volume depends on the size of the container
More pumps of air is added to the jar

Can be compressed?
Yes
Solid
Volume/Space
Definite
the total volume of the four equal smaller pieces
Same as
total volume of the original larger piece
Can be compressed?
No
Shape
Definite
When the solid cube is broken into 4 smaller pieces and are placed in a flask
The smaller pieces remains in the shape of a cube
they do not take the shape of the flask
