The City University of New YorkQueens College: Chemistry and BiochemistryChem113 Lab Report: Specific Heat Capacity of a MetalStudent Name: Instructor: Dr. Md Gias Uddin
Prelab Questions: (Points 2+2+1)1.100.0 mL of cold water at 20.5 oC was poured into a styroform coffee cup calorimeter. After adding 100.0 mL of hot water at 30.5 oC and mixing it thoroughly, temperature of the mixture was found to 24.7 oC. Find the heat capacity of the calorimeter. [Specific heat capacity of water is 4.184 J/goC. Assume density of water is 1.0 g/mL at both temperatures.]
2.A hot metal weighing 65.0 g was heated to 125 oC and dropped into 75.0 g of water kept at a room temperature of 20.6 oC in a calorimeter. Within a couple of minutes, water’s temperature increased to 26.8 oC and stayed constant at that temperature. If the heat capacity or calorimetry constant is 11.5 J/oC, find the specific heat capacity of the metal.
