In our daily lives, where cooling curve and freezing point determination can be observed or applied? c) Al Your question is solved by a Subject Matter Expert. From the cooling curve, we can infer that initially, the temperature falls rapidly. Remember, although the specific heat capacity is related to the temperature in Kelvin, the equation only asks for the change of temperature, therefore, either Celsius or .
