Matter
What is Matter and it´s 3 states?
Matter is anything that has volume and mass. The 3 states are Solid, Liquid and Gas.
What is Hardness? Examples?
How resistant is it to being scratched.
What is Density? What is the relationship between Mass and Volume?
It is a specific property that measures how much matter is packed into an object.
Density = Mass / Volume
What are the different types of changes? Define them.
Physical changes (affect some properties of matter) and Chemical Changes (it produces new substances).
What is Energy?
Anything that is capable of causing objects to change.
What are the 2 different properties of Matter ?
General Properties (Mass, Volume) and Specific properties (Hardness, Tenacity)
What is Elasticity?
How easily it recovers to its original shape when it is deformed.
How do we classify Matter?
Pure substance and Mixtures
What type of change is deformation and Rust ?
Physical and Chemical
Describe 6 types of Energy. Get 500 extra points (if you can explain all of them)
Kinetic, Electrical, Thermal, Luminous, Chemical, Nuclear.
How do we measure Mass and Volume?
Grams/Kilograms/Metric tonnes.
Cubic centimeters/Millilitres/Cubic metres
Define viscosity?
The viscosity of a liquid is its resistance to flow.
What is a Pure substance?
Made up of only one type of Matter.
What is a force? What are two main types of force?
Force is a direct cause of change in speed and deformation of a body.
Contact and Action at a distance force.
What are the 2 main types of energy sources.
Renewable and Non Renewable energy sources.
1 m3 is equal to how much cm3
1 m3 = 1000 000 cm3
What is compression?
It consist of squeezing something so that it becomes smaller.
What is Homogeneous Mixtures & Heterogeneous Mixtures ? Give examples.
They have a uniform composition and you can´t visibly see the different types of Matter.
They don´t have a uniform composition. You can visibly see the different types of matter that are present.
Explain the 2 effects of forces with examples?
Variation of position or Movement, Deformation in the physical shape.
What are the types of Non renewable sources..
Fossil fuels, Nuclear fuels etc..
What instruments do we use to measure mass and volume?
Weighing scale and Graduating cylinder
Name all the specific properties of Matter?
Hardness, Tenacity, Elasticity, Viscosity, Compressibility.
What are the different type of Materials ? Give examples
Natural Material and Man-made material .
What type of force is Magnetism and Gravity?
Action at a distance force.
What are the types of Renewable energy sources?
Biomass, Solar energy , Wind energy and Flowing water.
