Matter
Anything that occupies space and has mass.
What is matter?
A material that is made of two or more pure substances (elements or compounds)/.
What is a mixture?
The type of property that depends on the amount present.
What is an extensive physical property? (mass, volume, length)
The type of change when a gas changes into a liquid.
What is the physical change? (all state of matter changes are physical)
This state of matter has molecules that are tightly packed and only vibrate in place.
What is a solid?
A mixture of substances with two or more distinct phases (unevenly mixed).
What is a heterogeneous mixture?
The type of property that is independent of the quantity of material present.
What is an intensive physical property? (density, boiling/melting points, color)
The type of change that occurs when iron melts.
What is a physical change? (iron particles don't change into something else)
According to this concept, all matter is made up of particles that are in continuous random motion.
What is the kinetic molecular theory?
Water (H2O) is an example of this type of pure substance.
What is a compound?
The type of mixture sand and styrofoam would make.
What is a heterogeneous mixture?
The type of property that describes how a substance interacts with another substance.
What is a chemical property?
This type of change can be used to separate mixtures.
What is a physical change? (boiling, filtering, freezing are all physical changes that can separate materials in a mixture)
These states of matter can take the shape of the container that they are in.
What are liquids and gases?
The type of matter that has a uniform and unchanging composition.
What is a pure substance?
The type of mixture rubbing alcohol and water would make.
What is a homogeneous mixture?
Density is this type of physical property.
What is an intensive physical property?
The type of change that occurs when salt dissolves in water.
What is a physical change? (salt and water particles don't change into new particles, they just mix together)
This is how the motion of the molecules changes as matter moves from solid, to liquid, to gas.
What is they move faster (or further apart) (or more energetically)?
Because Iron can be represented by the symbol Fe, we can tell that it is this type of pure substance.
What is an element? (Compounds have formulas like NaCl or CO2)
These properties can be used to separate a mixture, but not pure substances.
What is a physical property?
This is how density would be calculated.
What is mass divided volume? (m/v)
Burning, rusting, tarnishing are examples of what type of change
What is a chemical change?
