Problem: A piece of metal weighing 57.3 g is heated to a temperature of 88.0°C and is then immersed in 155 g of water at a temperature of 21.53°C. After equilibration the temperature is 24.72°C. If CH2O = 4.184 J/g°C, what is Cmetal?A) .370 J/g°C B) .571 J/g°C C) 1.00 J/g°C D) 2.11 J/g°C E) .164 J/g°C

FREE Expert Solution

Use the concept of calorimetry where the colder water at 21.53°C absorbs the heat from the metal at 88°C to determine the specific heat of metal

Back in Calorimetry, we can setup the thermal equilibrium as:
