2. Heat of combustion - Wikipedia

   en.wikipedia.org/wiki/Heat_of_combustion

   The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it. The calorific value is the total energy released as heat when a substance undergoes complete combustion with oxygen under standard conditions.

3. Energy value of coal - Wikipedia

   en.wikipedia.org/wiki/Energy_value_of_coal

   The calorific value Q of coal [kJ/kg] is the heat liberated by its complete combustion with oxygen. Q is a complex function of the elemental composition of the coal [citation needed]. Q can be determined experimentally using calorimeters. Dulong suggests the following approximate formula for Q when the oxygen content is less than 10%:

4. Resting metabolic rate - Wikipedia

   en.wikipedia.org/wiki/Resting_metabolic_rate

   In counting energy expenditure, the use of a resting measurement (RMR) is the most accurate method for estimating the major portion of Total daily energy expenditure (TEE), thereby giving the closest approximations when planning & following a Calorie Intake Plan.

5. Specific energy - Wikipedia

   en.wikipedia.org/wiki/Specific_energy

   A nutritional Calorie is equivalent to a thousand chemical or thermodynamic calories (abbreviated "cal" with a lower case "c") or one kilocalorie (kcal). Because food energy is commonly measured in Calories, the energy density of food is commonly called "caloric density". [7]

7. Heat equation - Wikipedia

   en.wikipedia.org/wiki/Heat_equation

   In mathematics, if given an open subset U of R n and a subinterval I of R, one says that a function u : U × I → R is a solution of the heat equation if = + +, where (x 1, ..., x n, t) denotes a general point of the domain.
