We use energy to heat scrap metal from 25C. For every 5C we require 260 Joules. To what temperature can we raise the scrap temperature if we use the heat of the following system? CaC2 is used with CO to produce CaO and CO2. In the stockpile we have 1200 kgCaC2 available of which due to time restrictions we can only use 760kg.
