Introduction
Discuss “Importance of knowing fuel efficiency”
Pre-Requisites:
Combustion, Fuel
Activity:
Which fuels are preferred over others for different purpose and find out whether fuel efficiency the reason behind it, Make a table and find out various calorific values from internet and tell which is the best fuel on basis of calorific values
Real Life Question:
“How can fuel efficiency play a role in saving costs?”
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| calorific value. | The amount of heat energy produced on complete combustion of 1 kg of a fuel |
| kilojoule per kg | The calorific value of a fuel is expressed in a unit called kilojoule per kg (kJ/kg). |
| global warming. | A gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants |
| acid rain. | Oxides of sulphur and nitrogen present in air dissolve in rain water and form acids. Such rain is called acid rain. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Models of global warming | See how human activities are leading to global warming |
Real life uses :
Based on calorific values different fuels are chosen for different purposes
Practical examples around us
| Examples | Explainations |
|---|---|
| Coal is used in place of wood | It has higher calorific value |
What you learn in Theory:
Importance of calorific value, fuel efficiency, global warming, acid rain
What you learn in Practice:
How fuel efficiency can help in deciding the suitable fuel, measures against global warming
