Procedure Part A: Practice with the Mathematics This portion of the experiment is to get some practice using the mathematical framework for specific heat and heat transfer. Read the problem carefully and answer the following questions to solve the problem. Problem: A metal sample with a mass of 50 grams is placed in a pot of boiling water until they reach an equilibrium temperature of 100 C. The sample is then transferred to an insulating container full of 25 g of water at a temperature of 22 C. They reach an equilibrium temperature of 3459, what is the specific heat of the sample? What type of metal is the sample? 1. What is the temperature change of the metal sample? 2. What is the temperature change of the water in the insulating cup? S. How much heat is gained by the 25g of water? How much heat is lost by the metal sample (no need for a calculation, use logic to answer the question)? 4. Compare this to the values on the second page. What type of metal is the sample made up of? 5. Use the information above to solve for the specific heat of the metal sample?Explanation / Answer
heat lost by metal sample= heat gained by water for an insulating system (1)
heat lost by metal sample = mass of metal sample* specific heat of metal* temperature change
heat gained by water= mass of water* specific heat of water* temperature change
specific heat of water is taken as 4.184 J/gm.deg.c and that of metal = Cp
temperature change of water= 34.59-22= 12.59 deg,c
heat gained by water= 25*4.184*(34.59-22) joules =1317 joules
temperature difference of metal = 100-34.59 = 65.41 deg.c
under adiabatic condition, heat gained by water = heat lost by metal sample
1317= 50*CP*65.41
Cp =0.403 J/gm.deg.c
