Matter of Fact
Anything that has mass and takes up space.
What is matter?
Solid, liquid, and gas.
What are the three states, or phases, of matter?
Two or more substances mixed together, but not chemically bonded.
What is a mixture?
Matter that cannot be separated from any other substance and always has exactly the same composition.
What is a pure substance?
A pure substance that can not be broken down into a simpler substance and contains only one type of atom.
What is an element?
The energy an object has due to its motion.
What is kinetic energy?
The ability of a substance to allow heat to flow through it.
What is conductivity?
Those properties that are measured or observed when matter undergoes a change and becomes an entirely different kind of matter.
What is a chemical property?
Characteristics that describe how one kind of matter is different from another.
What are properties of matter?
The state of matter in which a substance has a definite shape and definite volume.
What is a solid?
When the parts of a mixture are noticeably different from one another.
Being composed of different parts in different combinations to make up the whole.
What is the composition of a substance?
The smallest chemical unit of an element.
What is an atom?
The natural (passive) movement within gases and liquids that spreads out particles from an area of higher concentration to an area of lower concentration.
What is diffusion?
Any characteristic of a substance that can be observed or measured without changing the composition or the identity of the substance. Use to observe or describe matter.
What is a physical property?
The ability of matter to burn in the presence of oxygen.
What is flammability?
What states of matter are changed during evaporation?
The change of phase from a liquid to a gas.
The state of matter in which a substance has a definite volume but not a definite shape.
What is a liquid?
When we can't see any of the individual substances in a mixture because the substances are so evenly distributed that it is difficult to distinguish one substance in the mixture from another.
What is a homogeneous mixture?
Being able to see through it versus not being able to see through it.
What is the difference between transparent and opaque?
A pure substance that contains two or more elements chemically joined in a fixed proportion.
What is a compound?
The ability of solids to be hammered, pressed, or rolled into thin sheets without shattering.
What is malleability?
The ability of matter to combine chemically with other substances to form new substances.
What states of matter occur during condensation?
A gas turns into a liquid.
The state of matter in which a substance has neither a definite shape nor a definite volume.
What is a gas?
What is a solution?
What is a molecule?
The physical property of a liquid to resist flowing. Usually decreases when heated (for liquids).
What is viscosity?
A reversible physical change that occurs when a substance changes from one state of matter to another, such as melting or freezing.
What is a phase change?
The ratio of a substance's mass to its volume; defined by the equation: D=M/V.
What is density?
One is the substance in a solution that gets dissolved and the other is the substance in which what is getting dissolved dissolves.
What is the difference between a solute and a solvent?
The "recipe", or ratio of elements, that always stays the same, that make up a molecule. Ex: glucose is always 6 C, 12 H, and 6 O atoms).
What is a chemical formula?
One is the unique temperature at which a solid form of a pure substance changes to a liquid and the other is the unique temperature at which the liquid form of a pure substance changes into a gaseous form.
What is the difference between melting and boiling points?
