Thermal physics
Study Thermal physics as part of Further mechanics and thermal physics for AQA A-Level Physics 7408. This topic hub connects the approved learning objectives to flashcards, MCQs, exam-style questions, answer explanations, revision notes, key terms, common mistakes, exam tips, and mini practice tests where those assets are published. Use the overview to separate definitions, equations, data analysis, graph interpretation, practical reasoning, and conceptual explanations before moving into the practice tools. For Thermal physics, pay close attention to units, assumptions, evidence and boundary distinctions so answers stay specific to the exact A-Level Physics context.

Key terms
Exam tips
- Understanding Temperature vs Internal Energy: Use the named model first, then write the relevant equation, substitute values with units, and explain the physical meaning in Thermal physics. Avoid swapping angular, linear, thermal, and gas-law quantities because the units and conclusions change.
- Specific Heat Capacity Calculation: To calculate the thermal energy transferred, use the formula E = m x c x Δθ, where E is the energy transferred, m is the mass, c is the specific heat capacity, and Δθ is the temperature change.
Common mistakes
- Temperature vs Internal Energy: Temperature is a measure of the average kinetic energy of particles in a substance, while internal energy is the total energy contained within a system, including both kinetic and potential energy of the particles. Temperature applies to the thermal state of a system, while internal energy is relevant when considering energy transfers and changes in state.
- Confusing Specific Heat Capacity with Thermal Energy: Remember that specific heat capacity (c) is the amount of energy required to raise the temperature of 1 kg of a substance by 1°C. Use the formula E = m x c x Δθ correctly to find the energy transferred.
