A student determined the calorimeter constant of the calorimeter. The student added 50.00 ml of cold water to 50.00 ml of heated distilled water in a styrofoam cup the initial temperature pf the cold water was 21.00 degrees celcius and of the hot water 29.15 degrees celcius the maximum temp of the mixture was found to be 24.891 degrees C the maximum temp of the mixture was found to be 24.81 celcius assume the density of water is 1.00g ml-1 and the specific heat is 4.184Jg-1K-1 Determine the ( I dont know how to make the sign of a triange) the T-final-T initial for the hot water and the cold water
