Question

3. Based on your results is the Conservation of Energy a valid assumption for this Calorimeter, so long as the time involved is relatively short? Justify your conclusion. Table 2.2 Aluminunm Ala leg Copper Tungsten Mw 221. 9 228.5 223.9 3.1 1. Combining eq(1) with eq(2) we see that; Solving this for C, gives; eq(3) Now using eq(3) calculate your experimental values of the Specific Heat for each of the three metal samples. Show work in the space provided. (10 points) Alurinum (200)(+61) C400a COPPer Tungsten 228.5)Cs.1) lub.3

Explanation / Answer

When metal is added to the water the thermometer takes time to read the temperature.Because water is a bad conductor of heat and heat is also lost in the surrounding.So it takes time for the thermometer to be in eqilibrium with hot water. Therefore energy conservation is valid if we take into account the lost energy in the surrounding.But without that energy conservation is not valid in this case.
