In this experiment you will measure the heat of combustion (delta Hc) of naphthalene. Report the values of the following:
Cv, the heat capacity of the system.
the internal energy of combustion, delta Ec, at 25 celsius of naphthalene.
the enthalpy of combustion, delta Hc, at 25 celsius of naphthalene.
the heat of formation of naphthalene at 25.
How do you find all of this? My temperature diference was 2.383 celsius and my wire was 0.
