Chapter 5, Heat and Temperature 5-8 Figure 5-5. Heat Transfer Examples1 5.7 Thermal Response Whether by radiation, conduction, convection, or a combination of these, the temperature response to the input (or output) of some specified quantity of heat varies from one substance to another. Specific heat is defined as the measure of heat energy required to increase the temperature of a unit quantity of a substance by a certain temperature interval. Specific heat capacity is typically expressed in units of joules per gram- kelvin (J g-1 K-1). Thus, two different substances with identical temperature measurements do not necessarily possess the same amount of heat energy. When exposed to the same amount of heat energy, a substance with a low specific heat warms up more than a substance with a higher specific heat. Table 5-4 lists the specific heat capacity of various substances. 1 The source of this and other material labeled COMET® is the COMET® website at https://www.meted.ucar.edu of the University Corporation for Atmospheric Research (UCAR), sponsored in part through cooperative agreement(s) with NOAA, U.S. DOC. ©1997-2017 University Corporation for Atmospheric Research.
