How many joules are 4500 kcal?

How many joules are there in 7.72 kcal?

To convert kilocalories (kcal) to joules (J), you can use the conversion factor: 1 kcal = 4,184 J. Therefore, to find the number of joules in 7.72 kcal, you multiply 7.72 by 4,184. This calculation gives you approximately 32,253.68 J. So, 7.72 kcal is equivalent to about 32,254 joules.

3.25 kcal is how much in joules?

To convert kilocalories (kcal) to joules, you can use the conversion factor where 1 kcal is approximately equal to 4,184 joules. Therefore, to convert 3.25 kcal to joules, you multiply 3.25 by 4,184, which equals about 13,600 joules.

How many joules are in 4kcal?

The conversion is 4.2 Joules per calorie, so 4 kcal is 16.8 kJ.

How is the energy value of food measure?

Joules (J) or kilocalories (cal) (kcal in Europe)

How many kilo joules in 3280 kilo calories?

3280 kcal = 13,730 kJ

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.

If an endothermic process absorbs 263 Joules how many kilo-calories are absorbed?

To convert Joules to kilocalories, divide the amount of energy in Joules by 4184 (the conversion factor between Joules and kilocalories). Thus, 263 Joules is equivalent to approximately 0.063 kcal.

If the kcal is 185 what is it in calories?

184,999.99989344 in 185 kcals 1 joule = 0.239005736 calories 1 kilocalorie (kcal) = 4184 joules 185kl x 4184 Joules x 0.239005736 calories = 184,999.99989344

What is the heat equivalent to 4200 joules?

4200 joules is equivalent to 1000 calories, or 1 kilocalorie (kcal).

How many joules are absorbed by the water with a mass of 0.5 kg in order to raise the temperature from 30 to 65?

1 joule = 2.39 X 10-4 kcal 65-30 = 35 degrees 1 kcal = 1 degree kg 35 degrees X 0.5 kg / 2.39 X 10-4 kcal/joulle = 73222 joules

Are kilo joules and kcal the same thing?

no, that's a conversion factor of 4.184

How many calories are in 1 kcal?

1 calorie is 4.1868 joules. This is referred to (or was when I was at school a long time ago) as the 'mechanical equivalent of heat' and is worth remembering, you can say 4.2 joules to a good approximation. So 1 kcal = 4,186.8 joules or 4.1868 kjoules if you prefer
