Atest tube containing 35.5 g of lead shot (pb) is placed into a beaker containing deionized water(di h2o) at 25 degrees celsius. the test tube is removed 15 minutes after the water in the beaker has reached its boiling point (210 degrees fahrenheit). the lead is then gently transferred to a coffe-cup calorimeter containing 50.0g of di h2o at 22 degrees celsius. the temperature is observed to be 65.4 degrees celsius. determine the specific heat of lead and calculate the percent error
