What will be the equilibrium temperature when a 245g block of copper at 285 degrees C is placed in a 145g calorimeter aluminum cup containing 825g of water at 12 C ?

  • physics - ,

    The sum of the heats gained is zero.

    heat added to heat copper+ heat added to water + heat added to alumium cup=0

    245*Ccopper*(Tf-285C)+825*Cwater*(Tf-12)+145*Caluminum*(Tf-12)=0
    solve for Tf
