a) Heat is often used as a sterilization method for stainless steel medical tools. Calculate the the final temperature that would be measured when 25.56 kJ is absorbed by a 500 g stainless steel dental tool if its initial temperature is 285 K. Use 54.9 g mol-1 as the molar mass of stainless steel, and 24.2 J mol-1 K-1 as the constant pressure heat capacity of stainless steel. Be sure to indicate the correct units in your final answer. b) Is this experiment measuring the change in internal energy or the change in enthalpy? Provide an explanation to support your answer.
