Document Summary

1mm = 1 x 10^-3 m or . 001 m. Water freezes at 273 degrees k and boils at 373 degrees k. 0 degrees k is the lowest attainable temperature. Water freezes at 0 degrees c and boils at 100 degrees c. Water freezes at 32 degrees f and boils at 212 degrees f. No matter what the size of the object, the density will stay the same. Volume of an irregular shape is measured by water displacement. Unit analysis = procedure of changing units to ensure to get the proper unit using conversion factors. Conversion factor = a fraction in which numerator and denominator are the same quantity but different units. Given unit x desired unit / given unit = desired unit. Dimensional analysis = converting one unit from another for the same measure.
