Short explanation
Recall how viscosity changes with increasing molecular size. This objective belongs to Properties and combustion of hydrocarbons within Carbon compounds as fuels and feedstock for AQA GCSE Chemistry 8462. A strong answer should use viscosity accurately, explain the chemistry behind the statement, and connect the idea back to the exact command in the objective. When revising, separate this point from neighbouring Chemistry ideas by naming the relevant particle, substance, process, calculation, observation, or structure before giving the final conclusion.
Key concepts
Why it matters
This objective helps connect Properties and combustion of hydrocarbons to exam-style questions, flashcards, and revision notes for Carbon compounds as fuels and feedstock.
Common mistakes
1 linked- Viscosity Misconception: Explain that longer hydrocarbon molecules have more surface area and stronger London dispersion forces, so viscosity increases with chain length.
