1/5 A chemist carefully measures the amount of heat needed to raise the temperature of a 1.72 kg sample of a pure substance from 17.4 °C to 39.0 °C. The experiment shows that 68.7 kJ of heat are needed. What can the chemist report for the specific heat capacity of the substance? Be sure your answer has the correct number of significant digits.
