1) a piece of aluminum of mass .2kg at temperature .2kg at temperature 20C is placed in beaker containing 1.5 kg of water at 80C. Find the final temp after equilibrium is reached
2) How much water at 20C must be added to 1 kg of ice at 0C in order to end up with everything at a final temperature of 10C.
3) A 2 kg piece of metal at 60C is added to .5kg of water at 0C. if the final equilibrium temperature is 28C, what type of metal is it?
4) Briefly describe a possible method for measuring the heat of combustion of a material.
