A hot piece of silver metal , 552.0g,in mass, was dropped into acup containing 332.8g of cold water. The final temperature of thewater is measured to be 18.2 celcius. It was determined that the water gained 1.238kJ of heat during the process. What was the initial temperature of the metal when it was dropped into the water?The specific heat of silver is 0.235J/C*g and the that ofwater 4.18.
