properties, gas laws
| Term | Definition |
|---|---|
| physical property | characteristic or property that describes matter; does not change or affect the identity of the matter when it is described or observed |
| chemical property | property or characteristic of matter that describes its ability to change into something new; something happens- bubbles, smell, blows up... |
| physical change | when a change occurs in one of its physical properties but does not affect the identity of the substance- it stays the same |
| chemical change | when a change occurs and the substance changes into something totally new |
| density | mass compared to volume |
| reactivity | when 2+ substances are combined and something happens (ex- bubbles, catches fire, changes color...) |
| malleability | ability to be pounded into thin sheets; pliable |
| ductililty | ability to be rolled into coils |
| conductivity | ability to transfer heat (or electricity) through it |
| viscosity | resistance to flow (how thick or thin it is and how easy it is to pour); affected by temperature |
| flammability | ability to catch fire and burn |
| kinetic theory | 3 faceted theory that describes matter and its behavior |
| Boyles Law | gas law- says that as a gas's volume increases, pressure decreases; inverse relationship "Boyle wants to be VP" |
| Charles Law | gas law- says that a gas's temperature and volume are directly related- that as temperature increases, so does volume "Charles likes to watch TV" |
| pressure | the number of times and strength of an atom (or substance) colliding with (or pushing against) the outer edge of a container |
| intermolecular force | force that holds atoms together with each other |
