Energy

From now until study leave, your chemistry HW will be revision and exam questions based on particular topics highlighted in the mock exam that you need to work on. The topic that I would like you to study this week is Energy (question 4 on 1). Below are some websites/video's to help you revise, but you will also need to use your notes and revision guides. Please revise the topic then have a go at the correct level of questions for your tier of entry.

Once you feel confident with this topic and you have done some focussed revision, have a go at the exam questions below. This paper is both higher and foundation. You should be aiming to get 100% on these, so if you don't know an answer, go back and look it up. I don't want to test what you already know, I want you go go back and revise what you don't know.
