    calorie is defined as what raises the temperature of a gram of water by one degree Celsius, so 890 times 33

  • Q = m * c * dT

    dT = 45 - 12 = 33 degrees Celsius

    m = 890 grams

    c = 4.186 Joules per degree change in Kelvin per gram

    890 * 4.186 * 33 Joules =>

    122942.82

    There are 4.186 Joules per Calorie, so we can actually make this nicer

    890 * 33 =>

    89 * 11 * 3 * 10 =>

    267 * 11 * 10 =>

    2937 * 10 =>

    29370 calories
