What is Fuel and Fuel Efficiency?
What is fuel?
Fuel is a substance that undergoes combustion to release energy, typically used to power engines or provide heat.
What are common types of fuels?
Common types of fuels include gasoline, diesel, natural gas, coal, and wood.
How is fuel efficiency measured?
Fuel efficiency is measured by the amount of energy produced per unit of fuel consumed, typically expressed as miles per gallon (mpg) for vehicles or efficiency percentages for appliances.
What factors affect fuel efficiency?
Factors affecting fuel efficiency include engine design, vehicle weight, aerodynamics, driving habits, and maintenance.
Why is fuel efficiency important?
Fuel efficiency reduces fuel consumption, costs, and environmental impact by minimizing emissions and conserving resources.
How can fuel efficiency be improved?
Fuel efficiency can be improved through technologies such as hybrid engines, aerodynamic designs, lightweight materials, and driving practices like maintaining steady speeds and proper vehicle maintenance.
What is a Fuel? and Effects of Burning Fuels – NCERT Class-8 Notes
What is a Fuel? and Fuel Efficiency Burning of Fuels Leads to Harmful Products- Class 8 NCERT Revision Notes: Fuel is a substance that releases energy when burned. Fuels are used to power vehicles, generate electricity, and heat homes and businesses. There are many different types of fuels, including fossil fuels, renewable fuels, and nuclear fuels. Fuel efficiency is a measure of how efficiently a fuel is used. It is the ratio of the amount of energy produced by a fuel to the amount of energy that is consumed. Fuel efficiency is important because it can help to reduce fuel costs and emissions.
