Matter and its three states
What is matter?
All living and non-living things around us are matter
Matter has mass and occupies space.
Light and heat are not matter because they do not have mass or volume
How do we measure mass and volume?
Mass = amount of matter in an object.
Mass is measured in grams (g) or kilograms (kg)
Balance
measure the mass of an object
compare the masses of two or more objects
electronic balance
If an object is placed in a container, we should
find the mass of the empty container
find the mass of the container and the object
Volume
amount of space object occupies
measured in cubic centimeters (cm3) cubic meters (m3), millilitres (ml) and litres (l)
Bigger object = larger volume
object has to be removed or displaced before another object can occupy its space
Is air matter?
Some matter is visible, but some matter is invisible.
Air is a matter that is invisible
it has mass and occupies space.
What are the three states and what are their properties?
Solid
definite shape and volume
cannot be compressed
Finding volume of solid:
pour and record the amount of water in a measuring cylinder
put the solid in the measuring cylinder.
record the difference of the water
some cannot be seen (glass)
Liquid
no definite shape, definite volume
cannot be compressed
finding the volume of liquid
use a measuring cylinder or syringe
put the measuring cylinder on a flat surface
Position the eye at the same level as the liquid level
Record the value of the marking that is at the lowest point of the curved liquid surface.
some cannot be seen (water)
when heated, liquid expands more than solid, and gas expands the most.
gas
no definite shape or volume
can be compressed
some gases have colour and can be seen
