The following information is given for n-pentane at 1 atm: boiling point - 36.20 Degree C Delta H_vap(36.20 Degree C) = 357.6 J/g melting point = -129.70 Degree C Delta H_fus(-l 29.70 Degree C) =116.7 J/g specific heat gas = 1.650 J/g Degree C specific heat liquid = 2.280 J/g Degree C A 26.20 g sample of liquid n-pentane .s initially at -73.30 Degree C. If the sample is heated at constant pressure (P = 1 atm). kJ of energy is needed to raise the temperature of the sample to 48.90 Degree C.
