is an object that contains no heat energy.
changing from a liquid to a gas.
the temperature at which a liquid turns into a gas. Boiling points depend on air pressure.
a temperature scale with the melting point of ice at 0 degrees and the boiling point of water at 100 degrees.
an attribute that can be used to help identify a substance. A characteristic property is not affected by the amount or shape of a substance.
any change that involves the formation of a new substance. A chemical reaction has reactants and products.
characteristics of a substance that are observed when it reacts or changes to produce one or more new substances.
a substance where two elements are chemically combined.
the decrease in volume when a substance is cooled down.
changing from a gas to a liquid.
conservation of mass
Conservation of Mass: matter (mass) cannot be created or destroyed. It only changes form.
density: the relationship between mass and volume or the amount of mass in a given volume. It is usually measure in grams per cubic centimeter (g/cm³).
dissolving: the process that takes a place when a solvent is mixed with at solute to make a solution
Distillation: the process of evaporating a solution and then condensing the various fractions back into a liquid in order to separate them.
.element: a substance that contains only one kind of atom. The smallest unit of matter.
energy: the ability to do work or cause change
Evaporate: to change from a liquid to a gas at or below the boiling point.
Expansion: the increase in the column of matter that occurs when matter is heated.
Fahrenheit: a temperature scale with the melting point of ice at 32 degrees and the boiling point of water at 212 degrees.
Freeze: the change in state in which a liquid turns into a solid.
Filtration: the process of separating a solid and a liquid by passing a mixture of the two through a mesh. The liquid that passes through the filter paper is called the filtrate and the solid remaining is the residue.
gas: phase of matter with no definite shape or volume. It fills its container.
Immiscible: a term used to describe liquids that are unable to dissolve in one another.
Kelvin: a temperature scale with the lowest possible temperature at the zero point, which is called absolute zero. On the Kelvin scale, ice melts at 273 degrees.
liquid: phase of matter with a definite volume but not a definite shape. Spreads to fill the bottom of a container.
mass: the amount of matter in an object.
matter: anything that has mass and takes up space.
Melting: changing from a solid to a liquid.
Melting point: the temperature at which a solid turns into a liquid. The melting point of a substance is the same temperature as it's freezing point.
Miscible: a term used to describe liquids that are able to dissolve in one another.
mixture: two or more substances mixed together but not chemically combined.
Phase Change: when a substance changes from one substance to another.
physical change: A change that alters the form or appearance of a substance but does not make the material into another substance.
physical properties: characteristics of a substance that can be observed without changing the substance into something else.
plasma: an ionized gas formed when heat energy is applied to a gas.
Phase or State:
Phase or State: solid, liquids and gases are the three phases or states of matter.
Product: a substance formed by a chemical reaction.
properties: characteristics used to identify or describe a substance.
Pure substance: either an element or a compound.
Reactant: the starting substance in a chemical reaction.
solid: phase of matter with a definite shape and volume.
Solute: the substance that dissolves in a solvent. Solutes may be solids, liquids or gases.
Solution: a homogeneous mixture of a solvent and one or more solutes.
Solvent: the substance in a solution that dissolves the solute.
Saturated solution: a solution that will not dissolve any more solute at a given temperature or pressure.
Soluble: the ability to dissolve in a solvent.
Temperature the measurement of a how hot an object is.
Thermal decomposition: a chemical reaction in which a compound is decomposed by heating.
Theory: when many scientists have made the same observations over a period of time.
volume: the amount of space matter takes up.
malleability: property that allows a metal to be hammered, pressed, or rolled into thin sheets.
states of matter:
states of matter: solid, liquid, gas, plasma
Conductor: any substance that allows heat and/or electricity to pass through it.
Insulator: Any substance that prevents heat and/or electricity to pass through it.
