Read the wording for your board, then hide it and explain Units and consistency in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The symbol and unit must remain consistent with the question, and a change of 1 °C equals a change of 1 K so the same numerical value can be used in kelvin.
