I watched a video online where it showed how you calculate a reaction that goes through multiple phase changes. 0 degrees to 170 degrees. In this video they had to split it up first calculating the energy from 0-100 degrees and then from 100-170 degrees. Is this something we will need to know for the test? Lavelle never mentioned it.
When substances change phases, their specific heats also change. If this is water, for example, the specific heats of water and steam are different and therefore need to be calculated separately and then added together for total heat added.
