Matter of Fact
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?
The process of organizing information.
What is classification?
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.
Matter that cannot be separated from any other substance and always has exactly the same composition.
What is a pure substance?
The smallest chemical unit of an element.
What is an atom?
The theory scientists have developed to explain why some things exist as solids, some as liquids, and still others as gases.
What is the kinetic theory of matter?
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?
Each kind of matter.
What is a substance?
The state of matter in which a substance has a definite volume.
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?
Another name for a pure substance.
What is a mixture?
A pure substance that contains two or more elements chemically joined in a fixed proportion.
What is a compound?
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?
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.
One is the change of phase from a liquid to a gas, while the other is the reverse change of phase from gas to liquid.
What is the difference between evaporation and condensation?
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?
Being composed of different parts in different combinations to make up the whole.
What is the composition of a substance?
What is a molecule?
Because there is much more space between gas particles and because gas particles have more kinetic energy than liquid particles.
Why does diffusion occur faster in gases than in liquids?
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?
One is when a substance goes right from a solid to a gas, without becoming a liquid first. The other is the opposite process, where a gas changes directly into a solid, without becoming a liquid first.
What is the difference between sublimation and deposition?
Usually measured in g/cm^3, 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?
Being able to see through it versus not being able to see through it.
What is the difference between transparent and opaque?
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?
The random movement of particles in a fluid (liquid or gas) caused by collisions with other atoms or molecules, named after the Scottish botanist who observed it in 1827. Diffusion is an example of it.
What is Brownian motion?
What is the difference between melting and boiling points?
The solid formed that gives a clue that a chemical change has occurred.
What is a precipitate?
