It depends on the temperature of the water.
1 calorie equals roughly 4.184 joules, and 1 calorie equals roughly 1 degree C in a gram of water. (the actual definition includes a specific temperature, I think about 3 degrees C).
So you could say that 1 gram of water contains roughly 4.18400 joules per degree above absolute zero, so 1 gram of near-freezing water is about 273 degrees * 4.184 joules/degree = about 1142 joules.
1 gram of protein is equal to 17 kilojoules
There are 9 kilojoules (kJ) in 1 gram of fat.
There are approximately 17 kilojoules (kJ) in 1 gram of protein.
There are approximately 17 kilojoules in 1 gram of protein.
About 29K/Cal
There are approximately 9 calories, or 37.7 kilojoules, in 1 gram of fat.
It depends on what...Fat contains 37 kilojoulesCarbohydrates contain 16 kilojoulesProtein - 17 kilojoulesAlcohol - 29 kilojoulesAnd water contains NO kilojoules
One gram of protein contains about 4 kilojoules (kJ) of energy.
There are approximately 4.18 kilojoules (kJ) in 1 liter of water.
9 calories (37.8 Kilojoules) in 1 gram of fat
There are 4 calories in 1g of carbohydrates.
That's going to depend on what temperature the water starts from.
