How do you you convert cal to joules?
1 calorie = 4.1858 joules 1 joule = 0.2389029576186153 calories As an example, convert 5 calories to joules. 1 calorie = 4.1858 joules, therefore 5 calories = 4.1858 x 5 joules = 20.929 joules. So when converting calories to joules, multiply the number of calories by 4.1858 to give you the number of joules.
What is 85x5?
425
How do you convert from killi joules to joules?
To convert from kilo joules to joules you have divide by 1000 as 1 kilo joule is equal to 1000 joules. E.g. 2 kilo joules equals 2000 joules.
What times what equals 425?
1 times 425 and 5 times 85 equal 425.
What is divisible by 425?
The multiples of 425 (which are infinite) are all divisible by 425 , including these: 425, 850, 1275, 1700, 2125, 2550, 2975 . . .
470 joules is how many calories?
1 calorie = 4.18 joules; 470 joules = 112 cal; 1 nutritional cal(Cal) = 1 kilo-cal = 1000 cal; 470 joules = 0.112 Cal
How many calories equal to 84 joules?
1 cal=4 joule. 84 joules=84/4=21 cal
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 is the energy value of food measure?
Joules (J) or kilocalories (cal) (kcal in Europe)
Convert 6.5kcal to Joules?
To convert 6.5 kilocalories to joules, you multiply by 4184 since 1 kilocalorie is equal to 4184 joules. Therefore, 6.5 kcal is equal to 6.5 x 4184 = 27,164 joules.
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 425 joules are absorbed from the higher temperature reservoir and 295 joules of that is passed onto the lower temperature reservoir how much work has been done by the system?
The work done by the system can be calculated by finding the difference between the heat absorbed from the high-temperature reservoir and the heat passed onto the low-temperature reservoir. In this case, the work done by the system is 130 joules (425 joules - 295 joules).
