Heat and Calorimetry

ANALYSIS On the first part of the experiment which is the determination of specific heat of metals. The obtained value of experimental specific heat of metal of aluminum and copper are 0.2152 calg-℃ and 0.0958 cal g-℃ , respectively. It is a must to work faster in performing this experiment because working in an air-conditioned room greatly affects the result of the temperature. For the temperature values, the final temperature of mixture should not increase more than 1 ℃ compare to its initial temperature of water/calorimeter for it will give you a high percentage error. Based on the data gathered it is observed that the higher the temperature that a metal will absorb, will lead to a lesser value of the specific heat of metal. While on the second part of the experiment which is the determination of latent heat of fusion of ice, two trials are conducted. The values of experimental latent heat of fusion are 79.16% and 82.27%. The part that was being observed was the initial temperature of water/calorimeter, if the value of it was wrong it really affects the computed value of the experimental latent heat of fusion. Other one is if the value of mass of ice is higher it will yields a lower value of latent heat of fusion. The possible sources of error in this experiment are wrong procedure, wrong reading of temperature, immersing the metal for a short period of time, wrong formula for the calculation, be sure that the initial data is already gathered and everybody in the group should work and observe to be able to know if there is something missing in the data.

CONCLUSION

The objectives of this experiment are to determine the specific heat of metals and to determine the latent heat of fusion of ice. These objectives are aimed after performing the experiment. Different metals have different properties and among to the two metals used, copper can absorb heat greater than aluminum. Every substance
