1. The problem statement, all variables and given/known data I've done 2 experiments, one was to find the specific heat of nickel and the other was to find the latent heat of fusion. For the nickel experiment, it involves heating the nickel in a test tube in a water bath, and then transferring the pellets to a Styrofoam cup. With the ice experiment, it involves crushing ice and adding it to water at 35 C until it reaches 5 C. There are questions about the errors and reducing them that I'm not sure about. 2. Relevant equations For the nickel experiment: 1. What was the greatest source of error in the experiment? 2. Suggest ways of reducing the source of error. For the ice experiment: 3. Determine the sources of error in the experiment. 4. Suggest ways of reducing error. 3. The attempt at a solution For 1. I think some of the hot water may have entered the calorimeter because when the experiment was conducted, there was water that condensed onto the inside of the test tube. So some of the hot water may have entered the calorimeter I think...I'm not sure I'm also not really sure if the Styrofoam cup may have absorbed some of the heat but when calculating, I took the cup to have zero specific heat. For 2: I'm not really sure about this. Would moving the test tube around in the water bath help to distribute the heat evenly? and maybe the thermometer should not touch the glass of the beaker either. For 3: Impurities in the ice might be one....and it was also assumed that initial temperature of the ice was zero. For question 4: I'm not really sure how these problems would be fixed.
