**CHAPTER VOCABULARY** You can participate online by providing explanations for vocabulary **in your own words**. You can give examples if it helps your explanation of words. You can do one or five or ten and you can add on to posts that have already been made if you would like to improve an explanation. Don't forget to leave your name beside text that you write. Any plagiarized entries will be deleted.

matter- Matter is anything that has mass or volume. (Andrew Park)

mass- Mass is how much amount of matter that a object has. (Andrew Park)

volume - the amount of space that a substance or object occupies (HeeSoo)

pure substance- Matter that is made of only one type of particles. (Andrew Park)

mixture element - a part or aspect of something abstract, esp. one that is essential or characteristic.(HeeSoo)

compound- pure substance made of two or more element.(Andrew Park)

heterogeneous mixture homogeneous mixture

physical property- a property or an aspect of something that you can visibly see and measure. Some examples are the color of an object, the ductility, malleability, and the density of an object. (Jordan)

state

melting point

boiling point-a temperature point where a substance starts boiling <= especially liquid, water's boiling point is 100˚c (Jordan)

malleable-ability for a metal to be beaten and change shapes. (Jordan)

ductile-ability for a piece of metal to turn into a piece of wire by stretching and pulling (Jordan)

solubility-the ability for a substance to mingle and dissolve into another substance <= usually in a form of solid going to liquid. (Jordan)

conductivity-the capability for a substance to catch on electricity or pick up heat. (Jordan)

density - the degree of compactness of a substance.(HeeSoo) chemical property flammability corrosion physical change-a change that is usually reversible, with no new substances forming, no new set of properties changing, and with small or no energy change. It can be physically observed and calculated (ex. density change, colour change, state change) (Jordan)

chemical change kinetic molecular theory-theory that explains the movement of particles in different states (Jordan)
