Experiment 301: Thermal Expansion Guide Question: 1.) In the performance of the experiment, cite the possible sources of error  and its effect in the computed values. What are the recommendations  then to minimize such error? The possible errors are: a.) The room temperature, the room temperature affect the computed  value by means where the experiment is held, since we are performing  in the laboratory with an air conditioned room, we must make the  experiment fast as we could. The cold temperature inside the room  makes the metal cool faster than normal temperature. b.) The   materials   inside   the   metal   tube   also   affect   the   experiment.  Materials inside the tube also contract or absorb heat that the steam  generator releases. Like the water that remain inside the metal tube  when conducting another trial, water is liquid and liquid expand more  faster than the solid metal that affect the expansion of solid.  c.) Wrong computation of result. One common error in the computed  value   is   the   human   error,   wherein   the   performer   is   the   one   who  conduct mistakes in a given problem. In order minimize the error, it  must be computed several times to be accurate. d.) Wrong measurement of the expansion base built-in gauge. When the  gauge stopped moving, that is the time to record the expansion. Wrong  measurement will create error.   2.) Would the result be different if the computed water was not drained  from the expansion tube? Why? The result would be different because the condensed water inside the  tube   would   absorb   heat   from   the   steam.   When   there   is   no

condensation inside the pipe, steam energy will not be subject to heat  reduction. 3.) From   the   result   of   the   experiment,   compute   for   the   coefficient   of  expansion for area and volume of the metals. 5
