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 $Q = mc\Delta T$

3. Key Terms

WorkThe product of force and displacement in the direction of the force; W = Fd.
EnergyThe capacity to do work, measured in joules (J).
Kinetic EnergyThe energy of motion; KE = ½mv².
Potential EnergyStored energy due to position or configuration.
PowerThe rate at which work is done or energy is transferred; P = W/t.
Conservation of EnergyThe principle that energy cannot be created or destroyed, only transformed.

Band 33 marks

2. 8. Calculate the energy needed to heat 1.5 kg of water by 10°C. Use $c = 4180\ \text{J/kg·K}$.

Band 43 marks

3. 9. Explain why a hot metal object and cooler water reach a common final temperature when placed together.

Band 54 marks

6. Extend: Apply the Idea

Band 5/65 marks

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
