DIMENSIONAL ANALYSIS

-Convert 1 quantity to another

Infinite Sig Figs occur when

-you have a counted quantity

-you have an exact measurement

NEVER START WITH A CONVERSION FACTOR

UNITS HAVE TO CANCEL LEFT TO RIGHT

Ex:

      8.00 m           100 cm           1 in     

    _______    x   ________  x  _______  =    315 inches

        1                    1 m              2.54 cm

Extra Notes:

Temperature: Average Kinetic Energy of the particles in a sample

K='C + 273.15

In Kelvin temperatures, there is no negative.

0 energy = 0 temperature

'F= 9/5 ('C) +32

'C= 5/9 ('F-32)
