Introduction
Today we are going to observe a video explaining the key problems and effects of hydrocarbon fuel burning.
Task
1. What are the three substances that most hydrocarbon fuels contain?
2. For what main purposes we burn hydrocarbon fuels?
3. Why are sulphur dioxide and nitrogen oxides bad when mixed with rain?
4. Particulates are...
5. What phenomenon is caused by the build up of soot in the air?
6. When carbon is oxidised it transforms to...
7. When hydrogen is oxidised it transforms to...
8. What global phenomenon developed by carbon dioxide?
9. What is the cause of incomplete combustion?
10. What poisonous gas is created by the result of incomplete combustion?
Process
Before watching the video, read through all the questions in the task. After reading them, watch the video and try to answer as many questions as you can. Multiple watch times are advised, but no more than 3 should be needed.
Evaluation
The answers to the questions:
1. Hydrogen, carbon and sulphur or H, C and S.
2. For transport (may specify), heat and electricity.
3. Because they create acid rain.
4. Small particles of carbon or soot
5. Global dimming.
6. Carbon dioxide or CO₂
7. Water or H₂O
8. Global warming.
9. A low amount of oxygen (O₂) in the burning process.
10. Carbon monoxide or CO .
If you got at least 8/10 answers right, then you have learned this topic quite well and should not require to revise it again.
If you have 6/10 or 7/10 answers right, then you have learned this topic well, but there is still room to improve so revision is recommended.
If you have 5/10 or less answers right, I would recommend to revise the topic again to improve your knowledge about it.
Conclusion
In summary, hydrocarbon fuel is a very needed resource of energy and many things could not work and live without it, but, after we looked at some of the negative effects of it, we should reconsider our massive dependance on them to save the environment and ourselves from the effects it can leave behind.
