The measurement of heat is called calorimetrycalorimetry , measurement of heat and the determination of heat capacity. Heat is evolved in exothermic processes and absorbed in endothermic processes; such processes include chemical reactions, transitions between the states of matter, and the mixing of two substances to form .....

The kilocalorie, or kilogram calorie, is the quantity of heat required to raise the temperature of 1 kg of pure water 1°C;; it is equal to 1,000 cal. The kilocalorie is used in dietetics for stating the heat content of a food, i.e., the amount of heat energy that the food can yield as it passes through the body; in this context, the kilocalorie is usually called simply the calorie. The amount of heat energy needed to effect a 1°C; temperature increase in 1 gram of water varies with temperature (see heat capacityheat capacity or thermal capacity, ratio of the change in heat energy of a unit mass of a substance to the change in temperature of the substance; like its melting point or boiling point, the heat capacity is a characteristic of a substance. ..... Click the link for more information. ); thus the temperature range over which the heating takes place must be stated to define the calorie precisely. The 15° calorie, or normal calorie, is widely used in chemistry and physics; it is measured by heating a 1-gram water sample from 14.5°C; to 15.5°C; at 1 atmosphere pressure. The 4° calorie, also called the small calorie or therm, is measured from 3.5°C; to 4.5°C; (water is most dense at 3.98°C;); the large calorie, or Calorie, is equivalent to 1,000 small calories. The average value of the calorie in the range 0°C; to 100°C; is called the mean calorie; it is 1-100 of the energy needed to heat 1 gram of water from its melting point to its boiling point. The calorie may also be defined by expressing its value in some other energy units. The 15° calorie is equivalent to 4.185 joulesjoule , abbr. J, unit of work or energy in the mks system of units, which is based on the metric system; it is the work done or energy expended by a force of 1 newton acting through a distance of 1 meter. The joule is named for James P. Joule. ..... Click the link for more information. (J), 1.162×10−6 kilowatt-hours, 3.968×10−3 British thermal units, and 3.087 foot-pounds; the 4° calorie equals 4.204 J; and the mean calorie equals 4.190 J. Two other calories sometimes used are the International Steam Table calorie, equal to 4.187 J, and the thermochemical calorie, equal to 4.184 J. When the calorie is used for precision measurement of heat energy, the particular calorie being used must be specified.Calorie a unit of heat that is not part of a system of units. Designation, cal. In addition to the calorie, the kilocalorie (also known as the large calorie) is widely used; 1 kcal = 1,000 cal. Originally, the calorie was defined as the quantity of heat necessary to raise the temperature of 1 g of water by 1°C. Neither the temperature interval within which the heating was performed nor its conditions had been defined prior to the late 19th century. Various calories have therefore been used: the 0°, 15°, 20°, and 25° calories as well as the average calorie and the thermochemical calorie. The 20° kilocalorie was used in the USSR from 1934 to 1957. This kilocalorie was equal to the quantity of heat (with an accuracy of up to 0.02 percent) required to heat 1 kg of water from 19.5° to 20.5°C. The First International Steam Table Conference (London, 1929) introduced the international calorie, defined as 1/861.1 of the international kilowatt-hour (kW-hr). The InternationalSteam Table Conferences in 1954 and 1956 accepted the decisionon transition from the calorie to a new unit, the absolute joule(J), which subsequently was included in the International Sys-tem of Units. The following relationship was established betweenthe calorie and the joule: 1 cal = 4.1868 J (exactly). The 20°calorie is equal to 4.181 J. The calorie used widely in thermo-chemistry is equal to 4.1840 J. calorie[′kal·ə·rē] (thermodynamics) Abbreviated cal; often designated c. A unit of heat energy, equal to 4.1868 joules. Also known as International Table calorie (IT calorie). A unit of energy, equal to the heat required to raise the temperature of 1 gram of water from 14.5° to 15.5°C at a constant pressure of 1 standard atmosphere; equal to 4.1855 ± 0.0005 joules. Also known as fifteen-degrees calorie; gram-calorie (g-cal); small calorie. A unit of heat energy equal to 4.184 joules; used in thermochemistry. Also known as thermochemical calorie. calorieThe heat required to raise the temperature of 1 gram of water 1°C; now called a small calorie.

Calorie1. a unit of heat, equal to one thousand calories, often used to express the heat output of an organism or the energy value of food 2. the amount of a specific food capable of producing one thousand calories of energy calorie
calorie [kal´o-re] any of several units of heat defined as the amount of heat required to raise the temperature of 1 kilogram of water by 1 degree Celsius (1°C) at a specified temperature. The calorie used in chemistry and biochemistry is equal to 4.184 joules. Symbol cal. See also nutrition. In referring to the energy content of foods it is customary to use the “large calorie,” which is equal to 1 kilocalorie (kcal). Every bodily process, including the building up of cells, motion of the muscles, and the maintenance of body temperature, requires energy, which the body derives from the food it consumes. Digestive processes reduce food to usable “fuel,” which the body “burns” in the complex chemical reactions that sustain life. The amount of energy required for these chemical processes varies. Factors such as weight, age, activity, and metabolic rate determine a person's daily calorie requirement. Nutrition experts have computed daily calorie requirements in terms of age and other factors. These tabulations serve only as guides; they cannot, of course, embrace all individual variations. From its daily intake of energy foods, the body uses only the amount it needs for energy purposes. The remainder is stored as fat. If the average adult consumes more calories than the daily requirement, he or she will gain weight. However, if consumption is less than recommended daily requirements, the body will supplement its energy sources by drawing upon stores of fat and the person will lose weight.cal·o·rie (kal'ō-rē), As used in nutrition and dietetics, this word ordinarily means kilogram calorie (kilocalorie).A unit of heat content or energy. The amount of heat necessary to raise 1 g of water from 14.5-15.5°C (small calorie). Calorie is being replaced by joule, the SI unit equal to 0.239 calorie. See also: British thermal unit.

Calorie is being replaced by joule, the SI unit equal to 0.239 calorie. See also: British thermal unit[L. calor, heat]calorie The amount of heat needed to raise 1 g of water by 1 C. For nutritional purposes the Calorie (or kilocalorie) is the amount of heat needed to raise 1000 grams of water by 1 C. The modern unit is the joule. 1 calorie is a little over 4 joules.calorie the heat required to raise 1 g (1 cm3) of water through 1 °C (i.e. from 14.5 °C to 15.5 °C). A Calorie (with a capital C) is used sometimes to denote a kilocalorie. The calorie was formerly used as a unit of energy content or output, but is now largely superseded by the SI unit joule (4.19 J = 1 cal).CalorieA unit of heat measurement used in nutrition to measure the energy value of foods.

[L. calor, heat]Patient discussion about calorieQ. In which sports do you burn the most calories? I heard that in a spinning session you can burn up to 1000 calories and that Bikram yoga is also very good for burning lots of calories. Do you know of other sports? A. Running and cycling are considered high-expenditure sports. Generally, the higher you get your pulse during the exercise the higher your calorie expenditure is. However, the burning fat is optimal at a certain pulse, usually not the highest you can get yourself to. You may read more here: http://www.nlm.nih.gov/medlineplus/exerciseandphysicalfitness.html
Q. Low calorie desserts - any suggestions? I’m having my in-laws for a dinner next week, and since my husband has started a diet lately I’m looking for a low-calorie desserts to end the low-fat meal I’m preparing. Any idea?A. You can find suggestions and recipes here: (http://www.foodnetwork.com/food/lf_hl_low_calorie/0,2661,FOOD_21616,00.html )
Q. Is it true that alcohol has lots of calories? if so, then how can it be that people who are alcoholics are not all very fat?A. Alcohol carries about 7 Kcal per gram. 1 gram of fat gives 9 kcal & 1 gram of carbohydrate gives 4 kcal. but vast amount of alcohol can suppress the need for food, so they can pass out every afternoon and forget eating. obesity is a better situation. trust me.
