Heat Capacity at Constant Volume

on . Posted in Thermodynamics

heat expansion 4At a constant volume, abbreviated as \(C_v\), all the heat added goes into raising the temperature.  The value of heat capacity depends on whether the heat is added at constant volume, constant pressure, etc.  


Heat Capacity at Constant Volume Formula

\(\large{ Q = n \; C_v \; \Delta T }\) 
Symbol English Metric
\(\large{ C_p }\) = heat capacity at constant volume \(\large{\frac{Btu}{F}}\)   \(\large{\frac{kJ}{K}}\)  
\(\large{ n }\) = amount of substance \(\large{lbm}\) \(\large{kg}\)
\(\large{ Q }\) = heat transfer \(\large{\frac{Btu}{hr}}\) \(\large{W}\)
\(\large{ \Delta T }\) = temperature differential \(\large{F}\) \(\large{K}\)
