Calories per gram ($"Cal/g"$) implies calories per gram associated with those calories. A change-in-food mass is associated with the $"Cal/g"$ units, and just like a change in position in $"m"$...
A joule is the amount of energy required to accelerate a mass of one $"kilogram"$ by one $"meter/second"^2$ over a distance of one $"meter"$ There is no direct conversion of...
It is important to realize that when the term 'nutritional calorie' is used, they mean kilocalorie (= $1000$ calories). It is known that 1 calorie is approximately $4.184$ Joules....
Remember that $"1 kcal"$ $=$ $"1 Cal"$ $ne$ $"1 cal"$, so this is the one where: $"4.184 J"$ $=$ $"1 cal"$. Therefore: $=> "2.5" cancel("k")cancel("cal") xx (1000...
The food Calorie (capital "C") is actually a kilocalorie ($1 xx 10^3$ calories)! Why would someone do this? Well, probably because it takes about 2 megacalories ($2 xx 10^6$) to...
By definition, $"1 cal"$ is the approximate amount of energy needed to raise the temperature of $"1 g"$ of water by $1^@ "C"$ at $"1 atm"$. In thermochemistry, this...
Step 1. Determine the conversion formula $1$ Joule $=0.000239$ kilo calories Step 2. Express as conversion factors $(1" Joule")/(0.000239" kcal")$ or $(0.000239" kcal")/(1" Joule")$ Step 3. Multiply given value...
To identify the independent and dependent variables you need to first identify what the variables are. Then you ask yourself, which variable will be affected if anything is changed? For...
