Question
1. A student determined the calorimeter constant of the calorimeter, using the procedure described in this module. The student added 50.00 mL of cold water to 50.00 ml of heated, water in a Styrofoam cup. The initial temperature of the cold water was 19.09 and of the hot water, 28.17 oC. The maximum temperature of the mixture be was found to oC. Assume the density of water is 1.00 g mi and the specific heat is 4.184 J g iK Calculate the heat lost by the hot water. Type equation here 2. A student determined the calorimeter constant of the calorimeter, using the procdure described in this module. The student added 50.00 mL cold water to 50.00 heated, distilled water in a styrofoam The initial temperature of the cold water was 19.09 oC and of the hot water, 28.83 oC. The maximum temperature of the mixture was found to be 23.64 oC. Assume the density of water is 1.00 g mL and the specific heat is 4.184 J glK Calculate the heat gained by the cold waterExplanation / Answer
q = m * s* dT
q = (50+50) * 4.184 *(19.09 - 28.17)
q = -3799.07 J
q = m * s* dT
q = (50+50)*4.184*(28.83 - 19.09)
q = 4075.21 J
