All matter has ___________ and occupies _____________.
All matter has mass and occupies space.
100
What are molecules?
Molecules are tiny particles that join together to make up all matter.
100
Water in solid form is called...
What is ice.
100
True or false: Liquids keep their size and shape when put in different containers.
What is false. Liquids keep their size, but take the shape of any container they are put in. Even though a liquid's shape my change, its volume does not.
100
True or false: Gas takes up space.
True.
200
All matter is made up of __________________.
What is molecules.
200
The ____________ of molecules and _____________ of movement of molecules determines whether matter is a solid, liquid or gas.
What is the layout and speed of movement of molecules determines whether matter is a solid, liquid or gas.
200
True or False: The melting point of all solids in the same.
What is false. Objects in solid form have different melting points.
200
Why can liquids be poured?
Their molecules flow.
200
How does a gas act in the environment?
A gas spreads out in all directions and fills up any area that it is in.
300
These are the three forms of matter.
What is solids, liquids, gases.
300
My molecules are packed tightly together and move very slowly.
What is a solid.
300
True or False: Solids take the shape of their container.
False.
300
How do molecules act in a liquid?
The molecules in a liquid have room to move around
300
Three examples of gases are:
oxygen, air, helium, hydrogen, nitrogen, carbon dioxide
400
"Properties" of Matter include characteristics such as _____________, ________________, and _______________.
These can include things like colour, texture, mass, volume, hardness, flexibility, absorbency, strength, buoyancy, melting point, magnetism, solubility, etc.
400
Adding ___________ affects the layout and speed of molecules.
What is heat.
400
Why can't solids take the shape of their containers or change their own shape?
Their molecules stick tightly together and cannot move much.
400
The gas form of water?
What is steam
500
Explain how some characteristics and physical properties such as melting point or boiling point help to distinguish materials from one another.
i.e., different materials have different melting points - water melts at 0 degrees Celsius compared to butter which melts around 32 degrees Celsius.
500
True or False: In some cases molecules flow.
True: Molecules in liquids flow.
500
The molecules of solids don't move around much, but rather, they _________ (move back and forth a small amount but do not leave their positions. Hint: Starts with "v"
What is vibrate.
500
What determines how quickly a liquid flows?
How fast a liquid flows depends on the strength of the molecule bonds. For example, honey is a liquid that flows very slowly because the bonds are strong. It would take a lot longer to fill a cup with honey than it would to fill the same size cup with water. The bonds that hold the molecules together in honey are stronger than those in water.
500
Gases exert ____________ in all directions.
What is pressure
