That which has mass and occupies space.
The smallest particle of an element that has the chemical properties of the element.
Two or more atoms.
Made of only one type of matter.
cannot be broken down into simpler substances
An element that exists as two atoms.
Made of 2+ elements can be broken down by chemical means
uniform composition throughout (toothpaste)
non-uniform composition throughout (rice krispies treats)
A change in state. (Like Density and specific heat)
after a reaction you have a new substance. (create something new, color change, bubbles)
solid to gas H2O(s)-> H2O(g)
gas to liquid H2O(g)-> H2O(l)
solid to liquid, H2O(s)-> H2O(l)
liquid to solid H2O(l)-> H2O(s)
It is the amount of heat it takes to raise the temperature of 1g of a substance by 1°C (or 1K)
(cold) absorb heat
(hot) releases heat.
A method of investigation involving observation and theory to test scientific hypotheses.
does not have a fixed shape but has a fixed a volume.
has neither fixed shape nor volume.
Has a fixed shape and volume.
Metal Physical Properties
solid High melting points, high density, Malleable, Conductor, shiny
Nonmetal Physical Properties
gas/liquids low melting points, low density, not malleable, not shiny
Weighing the difference
difference between two weights, first of the empty container before and then the full
an object is immersed in a fluid raising the water level. Then a measurement is taken of the level to find the volume of a fluid.
incapable of mixing
Energy cannot be
created or destroyed
can be converted into kinetic energy
total energy of molecular motion in a substance
is the measure of amount of heat contained within a object and doesn't depend on size.
The lowest specific heat will have
the highest temperature over time.
Melting and freezing points are the
a property that does not depend on the amount of matter present (temperature, or density)
a property that depends on the amount of matter in a sample (mass)
A chemical element that has properties of metals and nonmetals. It can be a conductor of heat and electricity.
