The following information is given for n-pentane at 1 atm:boiling point = 36.20°C ΔHvap (36.20°C) = 357.6 J/g melting point = − 129.7°C ΔHfus (−129.7°C) = 116.7 J/g specific heat gas = 1.650 J/g ⋅ °C specific heat liquid = 2.280 J/g ⋅ °C A 26.10-g sample of liquid n-pentane is initially at −51.40°C. If the sample is heated at constant pressure (P = 1 atm), how many kJ of energy are needed to raise the temperature of the sample to 65.30°C?

The following information is given for n-pentane at 1 atm:
boiling point = 36.20°C ΔHvap (36.20°C) = 357.6 J/g
melting point = − 129.7°C ΔHfus (−129.7°C) = 116.7 J/g
specific heat gas = 1.650 J/g ⋅ °C
specific heat liquid = 2.280 J/g ⋅ °C A 26.10-g
sample of liquid n-pentane is initially at −51.40°C. If the sample is heated at constant pressure (P = 1 atm), how many kJ of energy are needed to raise the temperature of the sample to 65.30°C?
