What are dietetic calories?
A dietetic calorie is equal to one kcal (1000 calories). The unit is Cal as opposed to cal
What represents the greatest amount of energy 1000 cal 500 Cal 100 kcal or 100000 J?
Tek a dump
How many kilocalories are there in 1 calorie?
1 kCal = 1000 Cal or I Cal = 1/1000 kCal
If there are 9kcal in 1g of fat how many in 1kg?
The difference between kcal and cal is 1000 cal = 1 kcal. However, we usually count food calories with kcal, and use kcal and cal interchangeably. Therefore, 9 kcal [Food Calories] = 9 cal. So, to the point: If there are 9 kcal in 1 g of fat, there are 9000 kcal in 1 kg of fat (1 kg = 1000 g).
How many kcal?
1 kcal = 1000 cal. 1 cal = 4.18 J
What is the abbreviation for calorie?
"cal." or "kcal."
How is the energy value of food measure?
Joules (J) or kilocalories (cal) (kcal in Europe)
What are the energy formulas involving specific heat mass and temperature change?
E = mass x sp ht x Δ°t (Finding Energy)where E (Energy) or Q (Quantity of Heat), mass (g), sp ht (aka specific heat, J/g°C*[typical] or cal/g°C or kcal/g°C), and Δ°t (temperature change). Finding Temperature ChangeDivide energy by mass multiplied by specific heat. Δ°t = Energy-- Mass * sp htIn order to find the final temperature (if problem is asking for this), add or subtract the original temperature and the new temperature together.Tf = original temperature +/- new temperatureIf energy is added, the temperatures will be added together; if energy is removed, the temperatures will be subtracted.Finding MassDivide energy by specific heat multiplied by temperature change. Mass = Energy------- sp ht * Δ°tFinding Specific HeatDivide energy by mass multiplied by temperature change. Sp ht = Energy------- Mass * Δ°tConverting Form of Energy (joules, kcal, and cal)Sometimes a problem will have E be shown in cal/g°C or kcal/g°C but will be asking for Joules or even vice versa. This means a conversion has to take place. Cal --> Joules and Joules --> cal-Calories (Cal) --> Joules (J)Multiply # cal by 4.184 Joules (J).Conversion Factor# cal x 4.184 J = Joules---------- 1 cal1 cal = 4.184 Joules-Joules (J) --> Calories (Cal)Divide # Joules (J) by 4.184Conversion Factor# J x 1 cal = cal--- 4.184 J1 Joule = 0.239005736 calKcal --> Joules (J) and Joules (J) --> Kcal-Joules --> kcal (Joules --> cal --> kcal)Divide # J by # kcal multiplied by 103Conversion Factor# Joules x 1 cal - * - 1kcal = kcal---------- 4.184J -- 103 cal1 kcal = 4,184 Joules 1 Joule = 0.000239005736 kcal-Kcal --> Joules (J) (Kcal --> cal --> Joules)Multiply # kcal by 103 cal by 4.184JConversion Factor# kcal * 103 cal * 4.184J = Joules (J)----------- 1 kcal --- 1 calAnother relationship that is good to understand: 1 kcal = 1000 (103) cal 1 cal = 0.001 (10-3) kcal
Is 3.25kcal the same amount of energy as 3.25jouls?
No, to convert from cal. to joules 1 cal. = 4.18400 joules , then 1KCal = (4.18400 *10^-3) joules so 3.25 kcal doesn't equal 3.25 Joules
HOW DO YOU Convert 675 kwh to cal?
675 kwh = 580,395,537 Cal = 580,296 kcal Source: http://www.convertworld.com/en/energy/kWh.html I think the kilocalorie (kcal) is the "calorie" that nutritionists use.
Convert 6.5kcal to Joules?
1 cal ~ 4.18 J <-- known 6.5 kcal = 6500 cal = 4.18 [J / cal] * 6500 [cal] = 27170 [J] or 2.72e+4 [J]
What is the difference between kcal and cal?
No there's not. Except on the back of food packets it is called Kcal's instead of calories. This answer is wrong. A food, or dietary Calorie is equal to 1000 calories, which is 1 Kcal (kilocalorie). A capital C is also used to designate a Kcal, or 1000 small calories. A small calorie is designated by a small c, and is equal to the amount of heat required to raise the temperature of 1 cubic centimeter of water by 1 degree centigrade at standard atmospheric pressure. The small calorie is most often used as a measure of heat in sciences such as Chemistry. This term is slowly being replaced using joules. See Calorie and joule on Wikipedia.
