• The temperature enter to the expansion device is 18.5
0C.
• The evaporator gauge pressure is 3.05 bar.
• The condenser gauge pressure is 10.7 bar.
• The volume flow rate at the evaporator entrance is 1.5

in a lab experiment to test the change in temperature
of NaCl and the change in temperature of water:
Specific heat of NaCl is 0.88
specific heat of DI water is 4.2
in the experiment, the change in temperature for the
water was much greater than the change in temperature of the table
salt as well as the change in energy.
(when using equation E = g C × change in T)
why did this occur?

LAB: The purpose of this experiment is to study the conditions
that must be satisfied for a rigid object to be in static
equilibrium. This is done by computing the total torque acting on a
meter stick by means of weights suspended at specific locations on
the ruler.
If a baseball bat (thicker on one side than the other) is cut at
the location where it balances, with both side be of equal
weight?
Can the meter stick be balanced...
