(HW5-27)
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 1.27 pounds of
butane (fuel value is 10.85 kcal/g) is used to heat 127.5 kg of
water at an initial temperature of 18.7 °C, what is the final
temperature?
calculate the amount of heat released by the burning methanol in joules
