Lecture 40: Kinetics and Thermodynamics Part III. Units for Measuring Heat Flow A.    Joules 1.    Heat is usually measured in joules, J a.    Heat cannot be measured directly, but is measured by temperature changes when  heat is transferred B.     Calories 1.    Heat is sometimes measured in calories 2.    A calorie is the amount of heat that will raise the temperature of one gram of water by one  Celsius (or Kelvin) degree 3.   1 calorie = 4.184 Joules Part IV. Heat Capacity and Specific Heat A.   Specific Heat 1.   The amount of heat required to raise the temperature of one gram of substance by one  Celsius degree (1 0 C) or one Kelvin (1 K) B.   Calculating Specific Heat 1.   Specific Heat ( c p ) 2.     q  = heat              m  = mass            T  = change in temperature (in Celcius or Kelvin) 3.    Formula; q = mc∆T
