GCSE Physics - Specific Heat Capacity | Internal Energy & Temperature (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. The concept of internal energy. The total energy stored by the particles within a substance or system. A breakdown into kinetic energy stores (related to temperature) and potential energy stores. 2. The relationship between heating, internal energy, and temperature. How transferring energy to a substance increases its internal energy. How temperature is a measure of the average internal energy of the particles. 3. The definition of specific heat capacity. The energy required to raise the temperature of 1 kg of a substance by 1°C. An explanation of why different materials heat up at different rates, with examples for water and mercury. 4. The specific heat capacity equation. An introduction to the formula ΔE = mcΔθ. A breakdown of each variable: change in internal energy (ΔE), mass (m), specific heat capacity (c), and change in temperature (Δθ). 5. Applying the specific heat capacity equation. A step-by-step worked calculation to find the final temperature of a substance. How to rearrange the formula and convert units correctly. 6. Practical considerations for experiments. The effect of energy being lost to the surroundings. Methods to minimise energy loss, such as using a lid and insulation. ** EXAM BOARD SPECIFIC INFO ** AQA - Everything is relevant to your course IGCSE Edexcel - Separate science and higher tier only Edexcel - Everything is relevant to your course OCR 21st Century - Everything is relevant to your course OCR Gateway - Everything is relevant to your course ** CHAPTERS ** 0:00 Introduction 0:20 What is Internal Energy? 1:02 How Heating Affects Internal Energy and Temperature 1:29 Defining Specific Heat Capacity 2:21 The Specific Heat Capacity Equation 2:49 Calculation Example 4:07 Practical Considerations: Energy Loss ** PLAYLISTS **    • KS3 Biology      • KS3 Chemistry      • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #GCSE #Physics #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE
