Question
A chemist carefully measures the amount of heat needed to raise the temperature of a 854.0 g sample of a pure substance from 13.9 °C to 19.2 °C. The experiment shows that 3.2 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.

**Answer Box:**

The answer box shows the units for the specific heat capacity as \( \text{J} \cdot \text{g}^{-1} \cdot \text{K}^{-1} \), indicating that the answer should be reported in Joules per gram per Kelvin.

**Input Controls:**

There is a control box with options for scientific notation (indicated with \( \times 10^ \Box \)), and buttons to submit or reset the input.
