Internal Energy Lab Calorimeter Cup
Procedures: The purpose of this lab was to
determine the specific heat of two different
metals. In order to do this, specific directions
were executed in order to discover the specific
heat. First, we needed to obtain and record the
weight of the Styrofoam calorimeter cup. Next, we
filled the cup 2/3 full with cool tap water and
recorded the temperature of the water. After this
was done, we filled a glass beaker half full with
water and placed it on a hot plate in order to

in decades, and of better quality than that of
many other countries. Accordingly, many Americans

incidents in the United States such as the
outbreak of the microorganism cryptosporidium in

That is something that will not be found since
unpurified tap water contains more than 500
chemicals. One of the most controversial issues
regarding our tap water is the fluoride that is
added to it. Approximately two-thirds of the
population of the United States are ingesting
fluoride into their bodies every day, if they use
tap water in any way. There are arguments that
