Physical Property
can be observed and measured without changing the kind of matter being studied
Melting Point
temperature at which a substance changes from a solid to a liquid
Boiling Point
temperature at which a substance changes from a liquid to a gas
Boiling Point of Water
100 degrees celcius; 212 Fahrenheit
Density
the relationship between the mass of a material and its volume
Chemical Property
can be observed when substances undergo a change in composition; the ability to react (combine) with another substance
Flammability
A material's ability to burn in the presence of oxygen
Reactivity
The ease and speed with which an element combines, or reacts, with other elements and compounds.
Formula for Density
Density = mass/volume
Physical Properties of Matter
Appearance changes: Melting Point; Boiling Point; Density; Color, Conductivity, Ductile
Malleable
Chemical Properties of Matter
reaction to other types of matter such as: flammability; reactivity
Conductivity
Ability to conduct heat or electricity
Ductile
Ability to be drawn out into a wire
Malleable
Ability to be flattened or spread out
Solubility
the physical property which describes how easily a substance dissolves or breaks down, and become liquid.
chemical reaction
the process by which one or more substances change to produce one or more different substances
Evidence of a chemical reaction
-production of gas
-formation of precipitate
-change in temperature
-change in color
-change in odor
Viscosity
A liquid's resistance to flowing
