Sublimation

A change directly from the solid to the gaseous state without becoming liquid

physical property

A characteristic of a pure substance that can be observed without changing it into another substance such as ;color,texture,density, crystal shape, boiling point and freezing point etc.

Pressure

Defined as the force of an object divided by the area measured in pounds per square inch or psi. Pressure increases as temperature increases. Gas particles move faster at higher temperatures. Gases are easy to compress because the particles are far apart.

liquid

Has a definite volume but no shape of its own, liquids take the shape of the container.

buoyancy

The ability or tendency to float in water or air or some other fluid if the objects density is less than the fluid it floats, if more than the fluid it sinks.

volume formula

The amount of space something takes up. For a regular object it is calculated by multiplying length x width x height. for an irregular object volume is found using water displacement.

Magnetic

The physical property of being magnetic attracting ferris metals.

Ductility

The property of a substance to be shaped or bent or drawn out into a thin wire without breaking.

Electrical Conductivity

The property of a substance to transmit electricity or electrons.

Malleability

The property of something that can be physically worked or hammered or shaped under pressure without breaking.

viscosity

a fluid's resistance to flow. As temperature decreases (gets colder) the viscosity increases-the material gets thicker, as temperature increases (gets hotter) the material gets thinner and flows.

fluid

a substance that flows

chemical property

ability of a substance to change into different substances

matter

anything that has mass and takes up space

atom

basic particle that makes up an element

boiling point

certain temperature that causes a substance to boil

vaporization

change in state from a liquid to a gas

freezing point

change of state from a liquid to a solid, the temperature at which a substance changes from a liquid to a solid

melting

changing states from a solid to a liquid

cubic centimeter

common unit of measuring volume of solids

gas

does not have a definite shape nor a definite volume

weight

force of gravity on an object

solid

has fixed, closely packed arrangement of particles which results in a definite shape and volume

density formula

mass / volume

physical change

matter changes its appearance but does not change into a different substance

law of conservation of mass

matter is not created or destroyed in any chemical or physical reaction

mass

measurement of how much matter an object contains measured in grams.

condensation

particles in a gas lose enough thermal energy to form a liquid

chemical change

produces new substances with different properties from those of the original substance

melting point

specific temperature at which a substance melts

sublimation

surface articles of a solid gain enough energy to become a gas and do not pass through the liquid state

density

the amount of matter in a given space

volume

the amount of space an object takes up

Molecule

the simplest structural unit of an element or compound when two or more atoms combine chemically they form a molecule.

evaporation

vaporization on a liquid's surface

boiling

vaporization throughout a liquid
