1. The problem statement, all variables and given/known data What is the final temperature of a mixture made from 3kg of ice at -5ºC and 10.8kg o fcopper at 2000ºC. The melting point of copper is 1083ºC. 2. Relevant equations Q=mct(delta)t mc(delta)t + mc(delta)t = 0J m=mass c=specific heat delta t = temperature change Q=energy 3. The attempt at a solution I have no attempt at such a question because I don't know how to attempt it with there being a phase change.
