Give two words.
It is matter if it takes up... and has...
Takes up space (or volume) and has mass (or weight).
100
Matter in which state can fill all the container completely?
Gas
100
Name at least 4 stages of the Water Cycle
Transpiration - evaporation - condensation - precipitation - runoff - accumulation (collection)
100
Name two state of matter changes: from a liquid into a solid and back.
Freezing and melting
100
What is the only matter that can be in all three states in everyday life?
Water
200
The building blocks (or units) of matter.
Particles (molecules, atoms)
200
Draw the particles arrangement for solid, liquid and gas.
Solid: packed closely, liquid: losely arranged, gas: arranged randomly and far apart.
200
At what stage of the Water Cycle does a cloud form?
Condensation
200
Name two state of matter changes: from a liquid into a gas and back.
Evaporation and condensation.
200
True or false? There can be a liquid metal at room temperature.
True. Mercury
300
What state of matter is it when particles are packed closely together?
Solid
300
This state of matter has a fixed shape and volume.
Solid
300
Rain, snow, hail, sleet are the types of...
Precipitation
300
When we cool down a gas it becomes...
...a liquid.
300
What matter can be liquid and solid at the same time?
Non-newtonian fluid (or oobleck).
400
In what state do particles move extremely quickly?
Gas
400
Name states of matter that can not be compressed.
Liquid and Solid
400
Where will evaporation be faster: in a tropical country or in Antarctica? Why?
In a tropical country. Because of the higher temperature.
400
What must happen with matter to change states?
Heat energy should be added to or removed from the matter.
400
Oxygen boiling point is -184℃. Is it solid, liquid or gas at -200℃?
Liquid
500
What happens with matter when its particles start to move faster or slower?
Matter changes its state.
500
This state of matter has a fixed volume but not a fixed shape.
Liquid
500
Describe what transpiration is.
Water moves through a plant and evaporates from leaves.
500
To what temperature should we warm up a solid to turn it into a liquid?
To the melting point.
500
The melting point of aluminium is 660℃. The melting point of iron is 1538℃. Which metal will you use to make a cup for melting the other one? Why?
A cup should be made of iron to melt aluminium in it. Melting point of iron is much higher.
