Unit 1 Question Bank
236 multiple-choice questions covering everything in the Topic 1 and Topic 2 booklets — engineers and impacts, sustainability, systems and control, energy forms, the five energy equations, power, efficiency and energy audits. Questions come up in a random order. Tap an answer and you are told straight away whether it is right, and what the correct answer is.

What's covered
Wrong answers are chosen deliberately. Most of them are the mistakes that lose marks in
this unit — leaving time in minutes, forgetting to square the speed, using the final temperature
instead of the change, giving a social impact when the question asked for an environmental one, or
calling a system automatic when a person is doing the controlling. If one catches you out, that is
the bit to go back over.
