I'm sure you are not expected to guess the formula. if you then have trouble applying the formula you could come back and ask for guidance. 18:59 Tue 05th Jun 2012 try (heat required) = (mass)(specific heat)(change in temperature) answer will be in joules. 19:05 Tue 05th Jun 2012 You know how many degrees the temp. of the water is raised, you know how much water there is, and you know how much heat is needed to raise the temp. of 1g. by 1C. 07:58 Wed 06th Jun 2012 522.5 Joules. See dr b's post. 09:40 Wed 06th Jun 2012 johnysid, he's supposed to work it out himself otherwise he won't learn. 17:46 Wed 06th Jun 2012 Er..r sorry ayee that should have been 'she'.
