BE CAREFUL- the flame may be nearly invisible.Ħ. Use matches or a lighter to ignite the fuel. Place the burner fuel on the pie plate just in front of the stand.ĥ. Place the beaker on the center of the stand.Ĥ. Set the burner stand towards the back of the pie plate.ģ. Place an aluminum pie plate on a solid work surface away from flammable objects.Ģ. Assemble the burner setup and light the fuel, as shown in Figure 14.ġ. The measurement is complete when the thermometer remains the same temperature without changing.Ģ. Note: When measuring the temperatures place the thermometer into the water so that the silver bulb is fully submerged, but not touching any sides of the glass beaker. Measure the temperature of the hot tap water with the thermometer in degrees Celsius (☌) to one degree of uncertainty. Fill the 100 mL glass beaker with approximately 75 mL of hot tap water.ģ. Let the water run as hot as possible for approximately 15 seconds.Ģ. Remember to do this any time you use this measuring device throughout the experiment.ġ. Note: Record every measurement you make with this thermometer to the same decimal place. Look at the calibration marks on the thermometer to determine the degree of uncertainty and number of significant figures that can be made when measuring temperature. Note: The thermometer is shipped in a protective cardboard tube, labeled "thermometer."ġ. Gather the 100 mL glass beaker, cup (plastic or drinking), matches or lighter, burner stand, burner fuel, thermometer, 2 oz. Convert the measurements for each of the objects from millimeters to meters and record in Data Table 1.ġ. Measure the length of each of the following objects (CD or DVD, Key, Spoon, Fork) with the ruler in millimeters (mm), to one degree of uncertainty, and record in Data Table 1.ģ. Measure the length of each of the following objects (CD or DVD, Key, Spoon, Fork) with the ruler in centimeters (cm), to one degree of uncertainty and record in Data Table 1.Ģ. Remember to do this any time you use this ruler throughout the experiment.ġ. Note: Record every measurement you make with this ruler to the same decimal place. Look at the calibration marks on your ruler to determine the degree of uncertainty and number of significant figures that can be made when measuring objects with the ruler. ![]() Gather the metric ruler, CD or DVD, key, spoon, and fork.Ģ. Finally, the aim will be to calculate concentrations of created solutions, calculate experimental error, and practice basic math and graphing skills.ġ. Additionally, the objective is to perform, compare, and contrast the water displacement and Archimedes' methods for measuring the volume of an irregularly shaped object. The goal is to perform measurements with a graduated cylinder, volumetric flask, graduated pipet, ruler, digital scale, beaker, and thermometer. The lab also aims to define length (meter), temperature (kelvin), time (second), volume (liter), mass (kilogram), density, and concentration, as well as to define significant figures and describe measurement techniques. Purpose of the experiment: The purpose of this experiment is to understand the International System of Units (measurement system), define a unit of measurement and demonstrate the ability to convert measurements.
