Classification Matter Flashcards
What are all objects around us made of?
Matter
Objects can be made of different types of what?
Materials
What are Thermal conductors
Materials that conduct heat
Malleable materials are?
Materials that are easily formed into different shape.
What are electrical conductors?
Materials that conduct electricity
Brittle materials are?
Materials that break easily
Ductile materials are?
Materials are able to be formed into long wires
Magnetic materials are?
Materials that have a magnetic field
What is density?
Is the mass per unit volume
What are boiling and melting points?
Tell us the temperature at which the substance will boil or melt. This helps us to classify substances as solids, liquids or gases at a specific temperature.
Define mixtures?
A mixture is a combination of two or more substances, where these substances are not bonded (or joined) to each other and no chemical reaction occurs between the substances.
In a mixture, the substances that make up the mixture are?
not in a fixed ratio
keep their physical properties
can be separated by mechanical means
What is a Heterogeneous mixtures?
It’s a mixture does not have a definite composition
Define Heterogeneous mixture?
A heterogeneous mixture is one that consists of two or more substances. It is non-uniform and the different components of the mixture can be seen.
Name of a liquid-liquid phase of matter?
emulsion
Name of a gas-liquid phase of matter?
aerosol
Name of a solid-liquid phase of matter?
suspension
Name of a gas-solid phase of matter?
smoke
What is a homogeneous mixture?
Is a mixture that has a definite composition, and specific properties
Define a homogeneous mixture?
A homogeneous mixture is one that is uniform, and where the different components of the mixture cannot be seen.
What is a pure substance?
Any material that is not a mixture, Pure substances include elements and compounds. It is much more difficult to break down pure substances into their parts, and complex chemical methods are needed to do this.
Define an Element?
An element is a substance that cannot be broken down into other substances through chemical means.
Define a compound?
A substance made up of two or more different elements that are joined together in a fixed ratio.
Define an Electrical conductor?
An electrical conductor is a substance that allows an electrical current to pass through it.
Define Insulators?
An insulator is a non-conducting material that does not carry any charge.
