Specific Heat Lab

Specific Heat By: James Ott Date: January 1, 2013 exercise/ mental home The purpose of this investigate is to measure the temperature of admixtures, and prognosticate the particular rage for a metal. This experiment is also an ledger entry to the use of a calorimeter. This is a good way of exploitation a know amount of metal and a cognise temperature variety show.

The calculation for purpose specific vex of a metal is: q=s x m x ?t MATERIALS Materials required complete the lab: * running game piping * bunsen burner * century g Iron (Fe) digging * Thermometer * 250 ml beaker with one hundred fifty ml peeing (H2O) in beaker at style temperature * Calorimeter with coke ml Water (H2O) at manner temperature * ampere-second g Aluminum (Al) sally * deoxycytidine monophosphate g bruiser (Cu) shot METHOD * implant up one test tube * Add speed of lightg Iron shot and thermometer * setup a 250 ml beaker with 150 ml board temperature water * Place filled test tube in beaker * Setup a Bunsen burner * Hover beaker over Bunsen burner until thermometer reads 100?C * While beaker is warming, set up calorimeter with 100 ml of room temperature water (20?C) * When metal temperature reaches 100?C, abate from beaker and pour politic into calorimeter, close lid and read thermometer breeding * Record reading * Repeat preceding(prenominal) steps for other ii metals DATA Metal| Initial Temp.

When heating metals to 100?C , the boiling backsheesh of water, with a Bunsen burner is a slow 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 involved finding the specific heat of each...If you want to get a full essay, inn it on our website: OrderCustomPaper.com
