what is the def of measurement
a number that shows how precise the tool used to measure the object is
what is the def of scientific notation
a equation created to condense large numbers that often appear in chemistry
what is the definition of mass
the quantity of matter present in an object
what is the definition for volume
the amount of three dimensional space occupied by a substance
what is the definition of density
a property of matter representing the mass per unit of volume
what is the definition of dimensional analysis
the changing from one unit to another via conversion factors based on the equivalence statements between units.
what is the definition of equivalence statement
the statement that states how many of one unit is in another
this has to have the same units as the question or it doesnt work
what is the def of conversion factor
one step problems that are meant to change the unit to the one in which you desire
what do positive exponents do
make numbers bigger
what do negative exponents do
make numbers smaller

what is the tool used to measure the volume of an irr. shaped obj.
graduated cylinder
which count as sig figs non zeros trailing zeros leading zeros captive zeros
nonzeros
captive zeros
trailing zeros only when an explicit decimal point is shown
when finding sigfigs after adding /subtracting what do you count
decimal places
when multiplying and dividing you count what
total sigfigs
what are the five steps for dimensional analysis
- question
- equivalence statement
- conversion factor
- do the math
- sigfigs
what is the freezing point for fahrenheit
32
what is the boiling point for farenheit
212
what is the freezing point for kelvin
273
what is the boiling point for kelvin
373
what is the freezing point for celcius
0
what is the boiling point for celcius
100
how do you convert kelvin to celcius
Tc= Tk -273
how do you convert celcius to kelvin
Tk= Tc+273
how do you convert celcius to farenheit
Tf= 1.80(Tc) +32
how do you convert kelvin to farenheit
Tf= 1.80(Tk) - 459
