liquid volume from the burettes.
2.
To measure the
temperature with a Celcius thermometer.
3.

vs. volume of a solid and liquid on rectangular coordinate graph paper and
observe a straight line plot.
5.
To plot
temperature change vs. time on a heating curve on rectangular coordinate graph
paper.
6.
To interpolate
the density of a liquid and solid from the graph plot of mass vs volume.
7.

EQUIPMENT:
Hardware from the desk: Equipment from check out cart/drawer:
Ring Stand 
100 mL Graduate 
Burette Holder 
5 Solid rubber stoppers no larger
than # 2 
Extension Clamp 
400 or 600 mL beaker 
Rings 5” and/or 3” 
100°C Thermometer 
Wire Gauze 
50 mL Erylenmeyer Flask 
Burners and tubing 
Burette brush (if available) 
Beaker tongs 
50 mL Buret 
Instruments: 
Special cut stopper to hold
thermometer 
Top Loading Balance (0.01g) 
Small Funnel for Buret 
PART A: TIME VS.
TEMPERATURE
(1)
Using a ring stand, Safety ring, ring, wire gauze, burner;
place a 400 ml beaker with it half filled with water on the ring stand to be
heated. Place a boiling chip in the water. (2)
Place a thermometer into the water by attaching it to an
extension clamp with a special cut thermometer stopper. Turn the divisions
read around so that you may view the entire division markings from 25° to
100° C. (3)
Adjust the ring on the ring stand to about two inches
above the top of the Fisher burner. Light the burner. Heat with the Fisher
burner. Record the temperature at each ˝ minute interval. When the water begins
to boil, continue heating for an additional two minutes, recording the
temperature every ˝ minute. Why may you stop after two minutes? (4)
Using beaker tongs, empty the water, cool the beaker,
refill with water at room temperature. Use a Bunsen burner instead of the
Fisher Burner. The distance between the ring and the Bunsen burner depends on
the flame height. Light the Bunsen
Burner. Adjust the burner for good blue flame, no yellow. Reheat and record
the temperature at each one minute interval. Heat the water to boiling and
boil for 2 additional minutes, recording the temperature every one minute.
Have your instructor OK your data. (5)
Plot time vs. temperature on graph paper. Put both plots
superimposed on the same graph. Make as smooth a curve as possible for both
heating curves. 

PART B: MASS VS.
VOLUME OF RUBBER
(1) Obtain
approximately 50 ml of water in a 100 ml graduated cylinder and record the
volume to the nearest 0.2 or 0.3 ml.
(2) The student will weigh on a Top Loading Balance a
size #2 or smaller rubber stopper. Then she/he will slide it gradually in the
graduate without spilling or splashing water. Record the mass and the new
volume to the correct number of decimal places.
(3) The student will weigh a second stopper, then add it
to the graduate Record the new volume.
(4) The student will continue until a third, fourth and
fifth is weighed separately and placed in the graduate. The volume is recorded
with each stopper as in step 3.
(5) Then the student will transform his/her data by calculating the mass and volume of
one stopper, two stoppers together, three stoppers together, four together, and
then all five together. The calculations will provide the student with five
points of increasing size to be plotted on the graph. Have your instructor OK your
final data transformation.
(6) On rectangular coordinate paper, plot these five
points. One axis of the graph will be mass, the other volume. Select the
numbering of the axis so to use the entire paper, yet all five points must be
included.
(7) Draw a straight line to incorporate all the points as
close as possible. Extrapolate so that the straight line crosses the axis, it
should cross the axis at 00 why?
The purpose of the straight line drawn in such a manner is to average
out the experimental error. Read the mass at the some volume other than a
recorded point, calculate the density. (Calculate the density from a second mass and volume reading).
Calculate the deviation and percent error
PART C: MASS VS.
VOLUME OF WATER
(1) The student will clean a burette, set it up, check
for grease spots. Rinse the burette with distilled water. Record the initial
volume. (Between 0.00 and 0.10 ml) (Burettes have division marking inverted.
0.00 is the starting point. The first line is read 0.10. Please see diagram
below :)
(2) Clean, dry, and weigh on the Top Loading Balance a 50
ml Erlenmeyer flask.
(3) Drain about 5 ml of water in the flask, record the
buret reading and reweigh the flask. Estimate
the buret reading to the nearest 0.02 or 0.03 ml. Have instructor OK the
second burette reading.
(4) In the same flask, drain 10 more ml of water and
record the buret reading (nearest
0.20.3 mL) and reweigh.
(5) Accumulate three more readings of approximately 10 ml
each (to the nearest 0.020.03 mL) until
you have used about 45 ml of water from the burette. Have your instructor Ok
your final reading. Check the temperature of the water and record it.
(6) Plot mass vs. volume on the graph. Read just your
reading into 5, 15, 25, 35, 45 ml points. Be certain to adjust the axis so that
you may use as much of paper as possible.
(7) Draw a straight line to incorporate all points, and
extrapolate the line to cross the axis at (0, 0). Read the mass at some volume other than a
recorded point. Calculate the density and compare to the correct from the
density temperature. Chart in Experiment 4. Calculate deviation and percent
error.
