Calculating specific heat examples
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 … WebTemperature (T) = 80.0 K. Specific heat (c) = 1676 KJ. Now we have to convert the specific heat into Joules because it is in Kilojoules. So, the …
