Properties of Matter
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
