a .250kg block of aluminum is heated to 100 C and then dropped into .60 kg of water that is initially at 20C. What is the equilibrium temperature of the system? The specific heat of aluminum is .22 kcal/kg C

    The sum of the heats gained is zero.

    heatgainedAl+heatgainedWater=0
    .250*.22*(Tf-00)+.6*c*(Tf-20)=0
    solve for Tf

    thanks!
