Question
Measuring the Calorimeter Constant (C To determine the calorimeter constant (C) of a nested pours 50.0 g of water at 24.32*C Into the calorlimeter. She then quickdy adds 50.0 g of hot water at 76.27*C and replaces the calorlmeter ld. She finds that the water hes a final temperature of 49.45'C. What is the value of the calorlmeter constant? The specific heat for water Is 4.184 cup" calorimeter, a student 14.0 ok q,, +q.+q,ai =0, where h = hot and c = cold 677 Do you know the answer MEDIUM Think so No Idea E)Explanation / Answer
Heat lost by hot water= heat gained by calorimeter+ heat gained by cold water
Heat lost by hot water= mass of hot water* specific heat* temperature difference
Heat gained by cold water= mass of cold water* specific heat* temperature difference
Heat gained by calorimeter= heat capacity of calorimeter* temperature difference
50*4.184*(76.27-49.45)= C*(49.45-24.32)+ 50*4.184*(49.45-24.32), C is the heat capacity of calorimeter
C= 14.06 J/deg.c ( A is correct asnwer)
