Studied by 5 peoplesolid particle arrangement
The particles are tightly packed.
The particles do not move around.
liquid particle arrangement
The particles are close together.
The particles vibrate, move, and slide past each other.
gas particle arrangement
The particles are very separated.
The particle vibrate and move quickly.
condensation
The change of state from a gas to a liquid
Matter
anything that takes up space and has mass
sublimation
A change of state from solid to gas
deposition
A change of state from gas to solid
chemistry
The study of the properties of matter and how matter changes
mass
the amount of matter in an object
volume
The amount of space an object takes up
weight
A measure of the force of gravity on an object
physical properties of matter
how matter is described according to physical characteristics; characteristics that can be observed without changing the substance into something else; ex. luster
physical properties examples
viscosity, conductivity, malleability, hardness, melting point, boiling point, and density
physical change
A change in a substance that does not change its identity
Chemical Properties of Matter
characteristics that can be observed when a substance interacts with another substance; ability to react; inability to react; usually hidden
chemical change
A change that occurs when one or more substances change into entirely new substances with different properties.
phase change
a change from one state (solid or liquid or gas) to another without a change in chemical composition
particles
extremely small units of matter (general term)
Viscosity
A liquid's resistance to flowing
surface tension
A measure of how difficult it is to stretch or break the surface of a liquid
amorphous solid
A solid made up of particles that are not arranged in a regular pattern
crystalline solid
A solid that is made up of crystals in which particles are arranged in a regular, repeating pattern
thermal energy
The total energy of motion in the particles of a substance (heat energy)
density
Mass per unit volume (D=M/V) (The amount of matter in a given volume)
physical properties of matter
characteristics of matter that are observable or quantifiable
chemical properties are observed…
by performing a chemical reaction
physical properties are observed…
without changing the composition of the matter
intensive
same regardless of the amount of matter
extensive
changes according to amount of the substance
intensive physical properties
color, odor, density, luster, thermal conductivity, malleability, ductility, solubility, elasticity
extensive physical properties
mass, volume, length, shape
