Chapter 15, Problem 94E

The following information is given for n-pentane at $1\text{atm}$:

$\text{boiling}\text{point}=36.20°\text{C}$ ${\text{ΔH}}_{\text{vap}}\left(36.20°\text{C}\right)=357.6\text{J}/\text{g}$

$\text{melting}\text{point}=-129.7°\text{C}$ ${\text{ΔH}}_{\text{fus}}\left(-129.7°\text{C}\right)=116.7\text{J}/\text{g}$

$\text{specific}\text{heat}\text{gas}=1.650\text{J}/\text{g}\cdot °\text{C}$

$\text{specific}\text{heat}\text{liquid}=2.280\text{J}/\text{g}\cdot °\text{C}$

A $26.10\text{-g}$ sample of liquid n-pentane is initially at $-51.40°\text{C}$. If the sample is heated at constant pressure $\left(\text{P}=1\text{atm}\right)$, how many $\text{kJ}$ of energy are needed to raise the temperature of the sample to $65.30°\text{C}$?
