Matter
Term | Definition |
---|---|
matter | -anything that has mass and takes up space -all matter is made up of tiny particles |
mass | -measure of the amount of matter in an object -the more mass an object has, the more particles an object has |
weight | how strongly gravity pulls on an object |
volume | how large or small and object is |
physical property | -a characteristic of matter that can be observed and/or measured -examples of physical properties are conductivity, reflectivity, solubility, magnetism |
conductivity | how energy such as electricity or heat can move through material |
reflectivity | way light reflects or bounces off an object |
solubility | ability of matter to dissolve a liquit |
magnetism | ability of a material to be attracted to a magnet without needing to be a magnet itself |
chemical property | -characteristic that can only be observed when there is a change in the type of matter -we can see her or smell the types of changes caused by chemical properties |
combustible | -being able to burn -some matter such as food products can change when they are heated or cooked |
corrosion | -some metals will react with air over time and cause it to rust or tarnish this is the process called corrosion -checmical property that cases them to react with air |
materials scientest | -tests how different materials can be used together -often try to combine matter into new materials with useful properties |
