Heat capacity at constant pressure, abbreviated as $C_p$, $is a measure of the amount of heat energy required to raise the temperature of a substance by one degree Celsius (or one Kelvin) while keeping the pressure constant.$ The heat capacity at constant pressure is an important thermodynamics property, especially in the study of gases and liquids. It plays a significant role in understanding how substances respond to changes in temperature and pressure. The value of $$C_p$$

Heat Capacity at Constant Pressure Formula
$\large{ C_p = \frac{ Q }{ n \; \Delta T } }$ (Heat Capacity at Constant Pressure) $\large{ Q = n \; C_p \; \Delta T }$ $\large{ n = \frac{ Q }{ C_p \; \Delta T } }$ $\large{ \Delta T = \frac{ Q }{ n \; C_p } }$
Symbol	English	Metric
$\large{ C_p }$ = heat capacity at constant pressure	$\large{\frac{Btu}{F}}$	$\large{\frac{kJ}{K}}$
$\large{ Q }$ = heat transfer	$\large{\frac{Btu}{hr}}$	$W$
$\large{ n }$ = amount of substance	$lbm$	$kg$
$\large{ \Delta T }$ = temperature differential	$\large{F}$	$\large{K}$
