|
|
Physical properties |
Characteristics of a substance that can be easily observed or measured. (density, magnatism, malleability, solubility, volume, shape, size) |
|
|
Malleable |
Of a metal or other material ..able to be hammered or pressed permentantly out of shape without breaking or cracking |
|
|
Physical change |
A change to a physical property; does not create a new substance |
|
|
Chemical change |
A change to a chemical property; creates a new substance( bubbling, tempature change, precipitant formed, gas produced, light emitted |
|
|
Precipitate |
A solid that is formed out of a chemical reaction of a liquid solution |
|
|
Ductile |
(Of a metal) able to be drawn out into a thin wire |
|
|
Luster |
A gentle sheen or soft glow, especially that of a liquid solution |
|
|
Luster |
A gentle sheen or soft glow, especially that of a partly reflective surface |
|
|
Conductivity |
Allowing the flow of heat and electricity to pass through a substance, such as a metal |
|
|
Insulator |
Blocking the flow of heat and electricity to pass through a substance, such as a non metal |
|
|
Law of conservation of masa |
Mass cannot be created or destroyed, it can only be converted from one formnto another |
|
|
What are the properties of metals? |
Shiny luster, malleable, ductile, conductor, high melting point |
|
|
If an element has a shiny luster, is malleable, can be drawn into a wire, and has great conductivity, is it a metal, non metal or matalloid? |
Metal |
|
|
What are the properties of non metals? |
Dull luster, brittle, insulator, low melting point |
|
|
What is a physical property? |
A characteristic of matter that can be easily obswrved or measures |
|
|
What is a physical change? |
A change to a physical property. Boiling water, melting ice cream, dissolving sugar |
|
|
How do you know when a physical change has occurred? |
A physical property is different, but the type of matter is the same. Ice melting, solid changing to a liquid. Its still water. |
|
|
What is a chemical change |
A change that alters the substance so ,uch that something new is created It is irreversible |
|
|
What are the ways to tell whether a chemical change has occurred? |
Matter changes into something new 1 production of odor 2 change in color 3 production of gas 4 production od precipitate 5 sudden change in light or temperature |
