Phases of Matter

Atom

The basic building blocks of matter, Atoms cannot be divided.

Boiling Point

The temperature at which liquid becomes a gas.

Chemical Property

A property that defines matter and how it interacts with other substances in the world.

Compress

To press or squeeze together.

Condensation

The phase change that occurs when vapor or gas cools and changes to liquid. Heat must be removed from the substance.

Condensation Point

The temperature at which a gas becomes a liquid.

Density

A physical property defined by dividing the mass of the substance by the volume.

Element

Substances that can't be separated into simpler substances and still act like the substance.

Evaporation

Slow VAPORIZATION

Freezing Point

The temperature at which a liquid becomes a solid.

Gas

Phase/state of matter where molecules move very fast, bounce off of each other. Indefinite shape and volume. Occurs after enough heat is added to a liquid.

Liquid

Phase/state of matter where molecules slide past each other and are not bonded to each other. Indefinite shape and definite volume. Occurs after enough heat is added to a solid to break the bonds. Takes the shape of the container.

Mass

A measure of how much matter there is in an object.

Matter

Anything that takes up space and has mass.

Molecules

The smallest part of a substance formed by chemical bonding. Water is and example of a molecule.

Melting Point

The temperature at which a solid becomes a liquid.

Phase

A physical condition or state of matter.

Physical Properties

The part of an object that can be experienced by using one of the 5 human senses (hear, see, smell, taste or feel)

Plasma

Phase/state of matter that has more energy than a gas. Plasma is different from a gas because it is made up of groups of positively (nucleus) and negatively charged particles (electrons) instead of atoms.

Property

describes how an object looks, feels or acts.

Solid

One state, or phase, of matter that is hard to compress and holds it's shape and has a definite volume. The atoms/molecules are bonded together in a set format where they vibrate in place.

State

A physical condition or phase of matter

Vapor

Another word for gas

Volume

The amount of space an object occupies.

Exothermic

Where heat is released

Freezing

Phase change from Liquid to Solid. Liquid loses energy.

Sublimation

Phase change from Solid to Gas. Dry Ice is an example.

Condensation

Phase change from Gas to Liquid. Water on the bathroom mirror or a ice water glass is an example. Gas loses energy.

Melting

Solid to Liquid. Solid gains energy.

Deposition

Phase change from Gas to a Solid without becoming a liquid. Frost is an example.

Vaporization

Phase change that occurs when a liquid atoms or molecules gain enough energy to change to gas.

Behavior of a substance during a phase change

Either absorbs or releases energy

Bose-Einstein

At super low temperatures (near absolute zero) atoms become super unexcited and super cold and clump together forming a super atom!

Boiling

Fast VAPORIZATION
