Physics Year 11 - Module 3 - Lesson 17
Thermal Energy, Temperature and Specific Heat Capacity
1. Key Ideas
Thermodynamics starts with a vocabulary trap: temperature, thermal energy, and heat are not the same thing. Once those ideas are separated properly, specific heat capacity and thermal equilibrium become much easier to reason about.
- The difference between temperature, thermal energy, and heat
- How kinetic theory links temperature to average particle kinetic energy
2. Success Criteria
By the end, you should be able to:
- The difference between temperature, thermal energy, and heat
- The meaning of specific heat capacity
- The equation $Q = mc\Delta T$

5. Short Answer Questions
1. 7. Distinguish between temperature, thermal energy, and heat.
2. 8. Calculate the energy needed to heat 1.5 kg of water by 10°C. Use $c = 4180\ \text{J/kg·K}$.
3. 9. Explain why a hot metal object and cooler water reach a common final temperature when placed together.
6. Extend: Apply the Idea
A student gives a memorised answer about Thermal Energy, Temperature and Specific Heat Capacity but does not use evidence or reasoning.
Improve the answer by writing a stronger response that uses accurate terminology, a relevant example and a clear explanation.
7. Multiple Choice
1. What is the best first step when answering a question about Thermal Energy, Temperature and Specific Heat Capacity?
A. Identify the key concept being tested
B. Write every fact from memory
C. Ignore the command word
D. Skip examples and evidence
2. Which answer would show stronger understanding of Thermal Energy, Temperature and Specific Heat Capacity?
A. An answer with accurate terms and reasoning
B. A copied definition only
C. A single-word response
D. An answer with no example
3. What should you do if a question asks you to explain?
A. Link the idea to a reason or cause
B. List unrelated facts
C. Only draw a diagram
D. Write the shortest possible answer
8. Success Criteria Proof
Finish with evidence that you can do each success criterion.
