question
Physical Change
answer
changes the shape or form of the object or material without changing it into a new substance
question
Chemical change
answer
changes the identity of one or more substances so that a new substance is formed
question
Physical proprties
answer
are properties that can be observed without making new substances Example: state, density,color, and hardness
question
Chemical Properties
answer
The ability of a substance to change into another substance or substances. Chemical properties many only be observed by changing or trying to change the substance into new substance.
question
Characteristic property
answer
is a physical or chemical property that does not depend on the quantity (mass or volume) of the substance-useful in identifying and classifying substances

question
State of Matter
answer
States of matter determined by a balance of forces among the particles. Particle Energies (temperature) causes them to move around and spread apart while the attractive Horses smaller particles cause them to stick together. How these forces balanced out determines the state of matter .
