A block of copper at 100 degrees Celsius comes in contact with a block of aluminum at 20 degrees Celsius. The final temp of the blocks is 60 degrees Celsius. What are the relative masses of the blocks?

  • Chemistry - ,

    [mass Cu x specific heat Cu x (60-100)] + [mass Al x specific heat Al x (60-20)] = 0
    You must look up the specific heat for the two metals, plug those into the equation and solve for mass Cu/mass Al.
