    1. The problem statement, all variables and given/known data

    A technician makes a 5.0kg metal object containing one part made of iron and the other aluminum. It takes 594 KJ to change the object temperature from 25 degree to 165 degree Celsius. what is the mass of each part?

    2. Relevant equations

    thermal energy

    3. The attempt at a solution
    no clue

    I have no clue right now either but from the problem you obviously need to know how much energy it takes to change each metal by 1 degree. Do you know a relation between energy and change in temperature which varies by substance?
