How many kilojoules in 1 gram of water?

Answer 1

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.
