Transcribed Image Text:# Calculating Specific Heat Capacity
A chemist carefully measures the amount of heat needed to raise the temperature of a 1.86 kg sample of a pure substance from 2.3 °C to 11.2 °C. The experiment shows that 12. 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.
### Units:
- Joules per gram per Kelvin (J·g⁻¹·K⁻¹).
### Interface Elements:
- **Input Box**: For entering the calculated specific heat capacity.
- **Check Button**: To verify the answer.
- **Explanation Button**: To access an explanation of the concept.
- **Reset Option**: To clear entries and start again.
- **Help Icon**: Provides guidance on using the interface.
### Instructions:
- Calculate using the formula for specific heat capacity \( c = \frac{q}{m \Delta T} \).
- Ensure the response is in the specified units and significant figures.
### Additional Resources:
- Explanation and theory can be accessed through provided links or help icons.
