03-00-03un
 Title Bumpersticker Caption The bumpersticker says "Cryogenics is cool." Research and industrial operations involving extermely low temperatures utilize cryogenic conditions. Keywords cryogenics, bumper sticker
03-02
 Title Wrenches with metric and English units Caption If you want a wrench that is the next size smaller than an 11-mm wrench, it's easy--use a 10-mm wrench. SI units are easier to work with than English units. If you have a 7/16-inch wrench, the next one smaller is marked 3/8-inch, not 6/16-inch (assuming the wrenches are in 1/16-inch intervals). Keywords English, metric, SI, units
03-05
 Title Metric volume relationships Caption One cubic decimeter has a volume equal to 1000 cm3; 1.00 cm3 equals 1.00 mL. Also, 1000 mL equals one liter. Keywords metric volume, decimeter, liter, L, mL, cm3, dm3
03-07
 Title Laboratory apparatus for volume measurement Caption Laboratory apparatus for measuring liquid volumes. Keywords metric volume, pipet, buret, graduated cylinder, flask, volumetric, measurement
03-09
 Title Mass balance Caption A simple balance. Keywords mass, balance, measurement
03-12
 Title Precision and accuracy Caption A dart board analogy of precision and accuracy. Keywords dart, precision, accuracy, uncertainty
03-13
 Title Uncertainty of volume measurement Caption A volume can be approximated to ±0.01 mL when the calibrations are shown in tenths, as they are in this figure. The volume 6.23 mL has three significant figures. Keywords uncertainty, significant figures, digits, measurement
03-14
 Title City signs Caption Which city has its population reported more precisely, based on significant figures? Keywords significant figures, round off, precision
03-14-01un
 Title Scientific notation, positive exponents Caption Scientific notation for exponent power of +2. Keywords scientific notation, exponent
03-14-02un
 Title Scientific notation, negative exponents Caption Scientific notation for exponent power of -3. Keywords scientific notation, exponent
03-15
 Title Factors of ten Caption What fraction is a drop in a 5-gallon bucket? Keywords drops, volume measurement, part per thousand, part per million, part per billion
03-17
 Title Mass and density of metal Caption The masses of 1.00 cm3 of several metals. For the metals shown, magnesium is the least dense and gold is the most dense. Keywords mass, density, metal
03-19
 Title Hydrometers Caption Hydrometers can be used to measure the specific gravity of a solution. (a) A hydrometer can be used to check the specific gravity of an antifreeze solution to determine the level of protection provided at cold temperatures. (b) The hydrometer shown here can measure specific gravities from 0.700 to 0.770. Keywords specific gravity, hydrometer, antifreeze
03-20
 Title Pycnometer Caption Pycnometers can be used for precise density and specific gravity determination for liquids. Keywords pycnometer, density, specific gravity
03-21
 Title Temperature scales Caption A comparison of the Fahrenheit, Celsius, and Kelvin temperature scales. Keywords temperature, measurement, scale, Fahrenheit, Celsius, Kelvin
03-22
 Title Heat energy Caption A bathtub of water at a given temperature has more heat energy than does a cup of water at the same temperature. Keywords heat energy, temperature
