First determine how many calories are required to raise the temp, then convert calories to Joules.

5 calories are required because the definition of calorie is the amount of heat necessary to raise 1 g of water 1 degree celsius.


 1 Joule = .239 calorie

So divide 5 by .239

your answer is 20.92 Joules
