Web... constant specific heat (usually assumed to be 414 J/kg-K) is not appropriate at temperatures below 250 K and temperatures above 700 K, as can be seen from Figure 1. The specific heat...
Webspecific heat, the quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree. The units of specific heat are usually calories or joules per gram per Celsius degree. For example, the specific heat of water is 1 calorie (or 4.186 joules) per gram per Celsius degree. WebSpecific heat is the amount of heat required to change the temperature of 1 gram of a substance by 1 Celsius. For instance, the specific heat of water in the solid phase is 2.059 J/gC and 4.184 J/gC in the liquid phase.
