A stream of liquid benzene is heated from $10\mathrm{.}0C$ to $40\mathrm{.}0C$ in a continuous process at constant pressure. Use the polynomial

expression below for the heat capacity to determine the change in the specific enthalpy of benzene in the process.

$C_{p}k\frac{J}{\text{m}\text{o}\text{l}*K}=a+bT$ with $TinC$ and

$a=126\mathrm{.}5{10}^{-3}k\frac{J}{\text{m}\text{o}\text{l}*K}$

$b=23\mathrm{.}4{10}^{-5}k\frac{J}{\text{m}\text{o}\text{l}*K^2}$

$widehat(H)=$

$k\frac{J}{m}ol$
