Energy transfer
The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.
Molar Specific Heat
Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)
Thermal Properties of Matter
Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which is transferred between the two systems or in between the systems and their surrounding by the virtue of difference in temperature. Calorimetry is that branch of science which helps in measuring the changes which are taking place in the heat energy of a given body.
Question
![Title: Understanding Heat Transfer in Substances
An experiment measures the temperature of a 700 g substance while steadily supplying heat to it. The results of the experiment are depicted in the accompanying figure.
**Graph/Diagram Explanation:**
- The graph shows the relationship between temperature (T) in degrees Celsius (°C) and heat supplied (Q) in kilojoules (kJ).
- The x-axis represents the heat supplied to the substance, ranging from 0 to 200 kJ.
- The y-axis represents the temperature of the substance, ranging from -40°C to 80°C.
- The graph displays a curve that starts at (-40, 0) kJ, rising gradually until it stabilizes, indicating a phase change, and then rises again.
**Questions:**
**Part A**
- **Question:** What is the specific heat of the solid phase?
- **Instruction:** Express your answer with the appropriate units.
- **Answer Box:** \( c_s = \) [Value] [Units]
