*** 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.
