Heat Capacity

Written by Jerry Ratzlaff on . Posted in Thermodynamics

open system 1Heat capacity, abbreviated as C or \(c_p\), is the amount of enerigy required to increase the temperature of a substance by 1°C.  The heat gain or loss results in a change in temperature and the state and performance of work.

Heat capacity formula

\(\large{ C = \frac {\Delta Q} { \Delta T }     }\) 

Where:

 Units English SI
\(\large{ C }\) = heat capacity \(\large{\frac{Btu}{F}}\)  \(\large{\frac{kJ}{K}}\) 
\(\large{ \Delta Q }\) = heat transfered amount \(\large{\frac{Btu}{hr}}\)  \(\large{ W }\)
\(\large{ \Delta T }\) = temperature differential \(\large{ F }\) \(\large{ K }\)
