100g of water at 30.0C is mixed with 150g of water at 85.0C. What is the final temperature of th mixture assuming no heat is gained or lost during the mixing process?

  • Physical chemistry -

    The sum of heats gained is zero (some of heats gained is negative,or lost).

    Heat100g gained+Heat150gained=0
    100*c*(Tf-30C)+150*c*(Tf-85)=0
    solve for Tf
