Matter has mass and occupies space.
Mass = amount of matter
Occupies space = has volume
(amount of space)
Not all matter can be seen e.g. air
Rolling dough or plasticine changes its
shape but not its volume or
Mass = amount of matter
Objects that have the same mass may not
have the same volume or shape.
eg. 1 kg of cotton wool is definitely much
BIGGER than 1 kg of iron because
cotton wool is lighter and needs more to
weigh the same as the iron.
The marble took up space in the water
so it has volume.
All the containers can store 500 cm³ of
oxygen because oxygen is a gas
and does not have a definite volume.
It can fill smaller or bigger
