The amount of energy released by burning a fuel source, measured in energy per mass, is called the fuel value. If all the energy obtained from burning 1.29 pounds of butane (fuel value is 10.85 kcal/g) is used to heat 122.5 kg of water at an initial temperature of 18.8 °C, what is the final temperature?

  • chemistry - ,

    Convert 1.29 lbs C4H10 to grams = ?
    Then ? g x 10.85 kcal/g = q kcal or 1000q cal.
    1000q = mass H2O x specific heat H2O x (Tf-Tinitial)
    Solve for Tf.
    I estimate the answer is about 71 C.
