Introduction to Calorimetry
Calorimetry literally means “heat measurement.” For consistency with other forms of energy and to avoid confusion, the modern unit for heat is the joule which equals 0.2390 calories. The unit for heat rate is the watt or J/s with prefixes m for milli (10−3), μ for micro (10−6), and n for nano (10−12). Heat can be measured in only three ways, referred to as “temperature change,” “heat conduction,” and “power compensation” (Hansen 2001). Table 1.1 lists characteristics of these methods.
