8LBs X 15 gallons x 54 DEGREES = 6480 CALORIES
q(Joules) = mass * specific heat * change in temperature
q = 85 grams * 4.180 J/gC *(65 C - 32 C)
= 11724.9 Joules
which is..........
2802 calories
q(joules) = mass * specific heat * change in temperature
q = 250 grams water * 4.180 J/gC * (85 C - 10 C)
= 78375 Joules
Using the tables at the attached link, it would take 75.303 kJ or 17.985 kcal.
It would take 1569 Joules, or 375 Calories.
You need to multiply all of the following together:* The mass
* The temperature difference
* The heat capacity of water

The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
Temperature is usually measured with a thermometer which tells you how many degrees Celsius or Fahrenheit the temperature is (Fahrenheit is the American measure and Celsius is what everyone else uses)
0 Degrees Celsius
Temperature is the head content of a matter. The temperature is measured in different scales and each scale has it uses and has originated for specific purposes. The well known measures of temperature are Fahrenheit and Celsius (or centigrade). Both Fahrenheit and Celsius are scaled between the freezing and boiling points of water. The freezing point of water is equal to 32 Fahrenheit and 0 Celsius and the boiling point is equal to 212 Fahrenheit and 100 Celsius. Another temperature scale is The Kelvin scale which has many applications in science and engineering. The start of the Kelvin scale (0 K) is the point of zero heat (no heat energy) which is equal to -273 Celsius.KelvinFahrenheitCelsiusIn degrees Kelvin, Celsius, or Fahrenheit.The most common unit for measuring temperature is degrees.
Melting, which is also known as fusion, and occurs at the same temperature as freezing, is a physical process that happens when there is a phase change from a solid to a liquid. This happens when the solid's internal energy increases (temperature increases) to a point where the solid melts into a liquid. At this point, the relatively well-ordered arrangement of molecules in the solid breaks down to a less ordered arrangement, being the liquid.

You will lose thermal energy.Heat (energy) will always flow from warmer to cooler.
Kelvin is a measure of temperature or thermodynamic energy, and is an absolute measure. Degrees Celsius are a used to measure temperature on a scale with an arbitrary zero.
21 Kg = 2100 grams to rise the temperature of this amount of water by 2 degrees Celsius you need 2*2100 = 4200 calories or 17572.8 Joules.
The energy required to raise the temperature 1 degree Celsius of 1 gram of water (1 mL) is 1 calorie (=4.18 J). So for 1 kg, 1Kcal (= 4180 J = 4.18 KJ) is required. To raise it 60 degrees, just multiply by 60 and for 10 kg multiply by 10 again. That would make 2.508 MJ (= 2508000 J) Now this is not completely accurate. The energy required to raise the temperature of water differs at 20 degrees from that at 60 degrees. The difference is small (~0.05 J or something like that) but still present.
