vocab
the amount of space a sample occupies
volume
the amount matter in an object
mass
A change in matter in which the substances that make up the matter change into other substances with different chemical and physical properties
chemical change
Matter that has a definite shape and a definite volume
solid
the mass per unit volume of a substance
density
Law that states that the total mass of the reactants before a chemical reaction is the same as the total mass of the products after the chemical reaction
law of conservation of mass
Matter with a definite volume but no definite shape
liquid
The maximum amount of solute that can dissolve in a given amount of solvent at a given temperature and pressure
solubility
states of matter
* gas
*solid
*liquid
Matter that has no definite volume and no definite shape
gas
The ability or inability of a substance to combine with or change into one or more new substances
chemical property
2 examples of a physical change
Melting, boiling, changing shape, mixing, dissolving, increasing or decreasing in temperature
explain what might cause the states to change from solid to liquid to gas?
An increase in temperature; as the temperature increases, the particles of water would move faster and farther away from each other
A characteristic of matter that you can observe or measure without changing the identity of the matter
physical property
A change in size, shape, form, or state of matter that does not change the matter’s identity
physical change
2 examples of a chemical change
Changing color, burning, rusting, formation of gas, formation of a precipitate, spoiling food, tarnishing silver, digesting food
Compare and contrast physical changes to chemical changes
the identity of matter does not change during a physical change, but the identity of matter does change during a chemical change. Also, the substance in a physical change is the same before and after the change whereas in a chemical change the substance is different after the change
