A unique pure substance that forms when two or more elements combine chemically. Ex. Water, (H2O) Carbon Dioxide (CO2)
Compound
The measure of the amount of matter within a substance.
Mass
The state of matter that has a fixed shape and a fixed volume.
Solid
Property of matter that can be observed without having to change its state.
Physical property
Property of matter that can be measured when matter undergoes a change to become an entirely different kind of matter.
Chemical property
The theory that all matter consists of constantly moving particles
Kinetic Theory of Matter
The unit used to measure mass
Grams or Kilograms
The state of matter that can have surface tension.
Liquid
An example of a physical property.
Multiple correct answers (odor, boiling point, melting point, ability to conduct heat, electricity, solubility, hardness, density, state of matter.
Ability of matter to combine chemically with other substances.
Reactivity
A homogeneous mixture with tiny particles.
Solution
The formula used to solve density.
Density=Mass/Volume
The particles of this state of matter always spread out to take up whatever space is available to it.
Gas
A change in one or more physical properties of matter.
Physical change
Ability of matter to burn
Flammability
A mixture that varies in composition. Ex. Pizza, cookie
Heterogeneous
The method used to measure the volume of an irregularly shaped solid.
The (Water) Displacement Method
The state of matter that resembles a gas but consists of particles that can pull apart and spread out.
Plasma
An example of a physical change.
Multiple correct answers (Melting ice, shredded paper, folding paper, cutting hair, chopping wood, breaking an egg)
A pure substance that cannot be separated into any other substances.
Element
A heterogeneous mixture where large particles are visible and settle to the bottom.
Suspension
The formula/method used to measure the volume of a regularly shaped solid.
By its dimensions: Length x width x height
Condensation
Even when matter undergoes a change, the total mass of matter always remains the same.
Law of Conservation of Mass
The smallest particle of an element that is in BOTH living and nonliving things.
