Specific Heat Chemistry Lab

Specific Heat of a Metal Some materials bespeak much muscularity to change its temperature than others. The amount required is dependent on 3 vari able-bodieds. The magnitude of the temperature change, the peculiar(prenominal) hot pants, and the mass. We conducted an experimentation in which we point the peculiar(prenominal) waken of a stress of a alloy. the habit of this is to by rights identify the metal condition to us. In this experiment we added heat to a container of weewee. meanwhile we took the mass of our metal have. We accordingly primed(p) the metal try out into a glass ravel pipework and placed the test tube into the boiling water. We measurable forbidden 100 mL of water and transfered it to a styrofoam form from our gradational cylender. Using the Vernier temperature probe connected to our laptop, we find the temperature of the metal sample in the boiling water. We transferred the metal sample to the syrofoam loving cup and ob served the temperature of the water with the hot metal sample in it. ::|Mass|Initial Temperature|Final Temperature (Water and Metal)| Water|100.0g|23.0ºC|27.0ºC| Metal|82.6g|89.0ºC|| We employ the specific heat grammatical construction to find the specific heat of our sample. The formula is: Q=cpm?T we apply a simple formula to find the heat nada that was gained by the water. That formula is: change in T= Tfinal-Tinitial |4.

0ºC| |62.0ºC| heat energy gained by the water|430 calories| specific heat of the metal|.08 cal/gºC| Our calculations cease with a result of .08 cal/gºC, henceforth we decided that our sample was of brass. Brasss specific heat is 0. 092 cal/gºC. Despite our best efforts co! llectible to equipment complications and the needed loss of heat to the enviroment due to styrofoams unabsolute insulating abilities our data was roughly off. through and through this procedure we throttled the specific heat of our sample. From this we were able to determine that the substance was brass. Our percent error was about13%, but the laboratory was make as well as possible given our lab...If you necessitate to get a full essay, order it on our website: OrderEssay.net
