density
A property of matter representing the mass per unit volume

New cards
physical change
a change in a substance that does not change the substance into a different one
3
New cards
chemical change
A change of one substance into another substance
4
New cards
melting
The process by which a substance changes from its solid state to its liquid state
5
New cards
melting point
the temperature at which a substance changes from its solid state to its liquid state through melting
6
New cards
freezing
the process by which a substance changes from its liquid state into its solid state
7
New cards
freezing point
the temperature at which a substance changes from its liquid state to its solid state through freezing
8
New cards
evaporation
a process by which a substance changes from its liquid state to its gas state by random particle movement. Evaporation usually occurs at the surface of a liquids over a wide range of temperatures
9
New cards
sublimation
the process by which a substance changes directly from its solid state to its gas state without becoming a liquid first
10
New cards
boiling
a process by which a substance changes from its liquid state to its gas state. The liquid is heated to a specific temperature at which bubbles of vapor form within the liquid
11
New cards
boiling point
the temperature at which a substance changes from its liquid state to its gas state through boiling
12
New cards
condensation
the process by which a gas becomes a liquid
13
New cards
law of conservation of mass
a law stating that no matter how energy is tranferred or transformed, it continues to exist in one form or another
14
New cards
chemical reaction
the process by which chemical changes occur. In a chemical reaction, atoms are rearranged, and chemical bonds are broken and formed
15
New cards
chemical equation
a short way to show a chemical reaction using symbols instead of words
16
New cards
coefficient
the number before a chemical formula that indicates how many molecules are involved in a chemical reaction
17
New cards
subscript
a number written slightly below and to the right of a chemical symbol that shows how any atoms of an element are in a compound
18
New cards
reactants
a substance that is present at the beginning of a chemical reaction and is changed into a new substance
19
New cards
products
a substance formed by a chemical reaction. A product is made by the rearrangement of atoms and bonds in reactants
