A 30-g iron bar at 100degreeC is placed in 200 g of water at 20degreeC. If the specific heat capacity of iron is 0.11 cal/gdegreeC, to what final temperature will the iron bar cool?

  • science -

    q = mcT
    Find the q for water (change in temp should be 100 - 20)
    q = 200(c)(80)

    Then solve for the final temp of the iron using -q.
