Part I. Specific Heat Capacity of Zinc Mass of metal Temperature of 50.0 mL tap water Temp of hot metal (think!) Final (maximum) temperature of water after adding hot metal Based on your data, calculate the specific heat capacity Cs of zinc following the steps below. 1) Calculate AT (Tfinal - Tinitial) for the water upon addition of the zinc piece. Indicate the +/- sign clearly. (Note: You can use Tfinal and Tinitial in °C to calculate AT in K. Why?) 31.269 20°C 91.5°C 23.9°c 2) Calculate the heat that the surrounding water gained (qsurr) from the metal. Indicate the sign clearly. (Assume 1.00g/mL. for tap water, and specific heat capacity C, for water is 4.184 J/g.K) 3) What is the quantity of heat lost from the metal piece (qys)? Show the sign clearly. 4) What is the AT of the zinc piece? Show the sign clearly. 5) Calculate the specific heat capacity C. (J/g.K) of zinc. 6) The literature value of the specific heat of zinc is 0.388 J/g K. Compare your result with this value and discuss the accuracy and possible sources of error. Part I.
