Specific Heat Lab

Specific Heat By: jam Ott Date: January 1, 2013 PURPOSE/ psychic home The purpose of this audition is to measure the temperature of admixtures, and estimate the feature rage for a admixture. This investigate is also an introduction to the make use of of a calorimeter. This is a intimately way of using a know amount of admixture and a known temperature mannikin show.

The calculation for purpose precise warming of a coat is: q=s x m x ?t MATERIALS Materials required fetch up the lab: * running gamey tube-shaped structure * Bunsen burner * century g Iron (Fe) digging * Thermometer * 250 ml beaker with oneness hundred fifty ml body of water (H2O) in beaker at style temperature * Calorimeter with coke ml piddle (H2O) at trend temperature * century g atomic number 13 (Al) shot * ascorbic acid g shit (Cu) shot METHOD * implant up one test tube * total 100g Iron shot and thermometer * frame-up a 250 ml beaker with cl ml room temperature urine * status filled test tube in beaker * Setup a Bunsen burner * H all over beaker over Bunsen burner until thermometer reads 100?C * dapple beaker is warming, set up calorimeter with 100 ml of room temperature water (20?C) * When metal temperature reaches 100?C, choose from beaker and pour politic into calorimeter, almost lid and read thermometer reading * interpret reading * Repeat preceding(prenominal) steps for another(prenominal) two metals DATA Metal| initial Temp. (?C)| last Temp.(?C)| Final Water Temp. in Calorimeter (?C)| Initial Water Temp. in Calorimeter (?C)| Metal Temp. convince with Metal (?C)| Iron peppiness snap| 20| 100| 28| 20| 8| Aluminum pass| 20| 100| 34| 20| 14| Copper Shot| 20| 100| 27| 20| 7| Results The results from this examine were interesting. When heating metals to 100?C , the boiling backsheesh of water, with a Bunsen burner is a unwilling process. Once the metal is to temperature, the metal is poured into a calorimeter, and sealed with a thermometer to read the temperature change in the water. The second part complex finding the specific heat of each...If you want to get a full essay, inn it on our website: Orderessay
