What is used to measure our mass?
A bathroom scale.
Say two examples of synthetic materials.
Rubber and plastic.
What are the two types of properties of matter?
General properties and specific properties.
Say 4 examples of unit of mass.
Kilograms, grams, miligrams and tonnes.
True or false:
The shape of a container affects how the same volume looks.
True.
What's matter?
It is anything that occupies space.
What are the general properties of matter?
Mass, volume and density.
What do we use to measure the mass?
We use scales.
What's volume?
It’s the space the matter occupies.
How can we convert kilograms to grams?
We multiply by 1000.
What's density?
It’s the relationship between volume and mass.
What do we do to convert grams to kilograms?
We divide by 1000.
What's capacity?
It's the maximum amount of liquid a container can contain.
What's mass?
Mass is the amount of matter in an object.
What is the unit to measure volume?
cm3= cube centimetres.
TRUE OR FALSE:
In a cube, length and width measure the same, but height is lower.
