Energy Change Q=mcDeltaT - AQA GCSE Chemistry Calculation Practice Book

Q = mcDeltaT appears in both the Chemistry and Biology papers but students rarely get enough dedicated practice with it. This AQA GCSE Chemistry workbook builds real confidence with 12 scaffolded questions using the EVERY method framework.

The EVERY method breaks each calculation into clear steps: Equation, Values, Enter values into the equation, Rearrange if needed, Your units. Every question has a structured EVERY table for students to complete, building a consistent problem-solving habit. Questions get progressively harder: Q1-3 are straightforward, Q4-6 introduce unit conversions, and Q7-12 require rearranging the formula.

What's inside:

- 12 progressive questions on Energy Change (Q = mass x specific heat capacity x temperature change)

- Structured EVERY method table on every question page

- Progressive difficulty: simple substitution, then unit conversions, then rearranging

- Self-assessment tracker with "What made me stuck?" reflection checklist

- Full worked answers for all 12 questions using the EVERY method steps

AQA specification reference: 5.4 Chemical Changes (Combined Science and Triple Chemistry)

Energy change calculations require students to calculate the energy transferred during exothermic and endothermic reactions using mass of solution, specific heat capacity of water (4.2 J/g/C), and the temperature change recorded.

Common student mistakes this workbook addresses: using mass of the solid reactant instead of mass of the solution, forgetting that temperature change means final minus initial (not the other way), confusing temperature with temperature change, and not converting from J to kJ when required.

Suitable for AQA GCSE Combined Science and Chemistry (Triple). Works for both foundation and higher tier students.
