Properties of Matter
A property that depends on the amount of matter, like mass or volume.
What is extensive property?
In this state, particles are tightly packed in a fixed volume and shape.
What is a solid?
A pure substance made of two or more elements chemically combined, like H₂O.
What is a compound?
The process of a liquid turning into a gas at its boiling point.
What is boiling (or vaporization)?
The smallest unit of an element that still has the properties of that element.
What is an atom?
A property observed without changing the substance's identity, like color or density.
What is a physical property?
This state of matter has a definite volume but takes the shape of its container.
What is a liquid?
A mixture that is not uniform in composition, like granite or a salad.
What is a heterogeneous mixture?
The direct transition from a solid to a gas, skipping the liquid phase.
What is sublimation?
A neutral group of two or more atoms held together by chemical bonds, such as O₂ or H₂O.
What is a molecule?
This intensive physical property describes a substance's ability to be hammered into thin sheets.
What is malleability?
This state is characterized by particles that are far apart and move randomly to fill any volume.
What is a gas?
A mixture that is uniform throughout and is also known as a solution, like saltwater.
What is a homogeneous mixture?
The temperature at which a substance changes from a solid to a liquid.
What is the melting point?
The formula used to calculate this key intensive property is mass divided by volume (D=m/V).
What is density?
A property that is independent of the amount of substance, such as boiling point or density.
What is an intensive property?
This theory states that all matter consists of tiny particles that are in constant, random motion.
What is Kinetic Molecular Theory?
The simplest form of a pure substance that cannot be broken down by chemical means.
What is an element?
The transition of a gas directly into a solid, like the formation of frost.
What is deposition?
This fundamental law states that mass is neither created nor destroyed in any chemical reaction.
What is The Law of Conservation of Mass?
The ability of a substance to undergo a specific chemical change, such as flammability or reactivity with acid.
What is a chemical property?
This high-energy state of matter, consisting of ionized gas, is the most abundant in the universe.
What is plasma?
This category of matter includes both elements and compounds.
What are pure substances?
A phase change is always accompanied by a change in this form of energy.
What is thermal energy (or heat)?
The energy of motion; the average of this energy in a substance's particles is measured as temperature.
What is kinetic energy?
