Question
________ cars emit more nitrogen oxides than petrol cars
- Hybrid
- Diesel
- Electric
- CNG
Hint:
It is cheaper than petrol and is in liquid form.
The correct answer is: Diesel
Desiel cars emit more nitrogen oxides than petrol cars
A diesel engine runs at higher temperatures and pressures than a gasoline engine. These conditions favor the production of NO gas. A diesel engine emits less CO2 and greenhouse gases than a gasoline engine. This is due to the special type of fuel and the internal efficiency of diesel engines. More specifically, the fuel used in diesel engines has a higher compression ratio than gasoline and is more powerful than gasoline engines.

The most important cause of air pollution is:
The correction of is c)Burning fossils fuels.
- Air pollution is a mixture of harmful substances from man-made and natural sources. Motor vehicle emissions, fuel oil and natural gas used to heat homes, by-products of manufacturing and power generation, especially coal-fired power plants, and smoke from chemical manufacturing are the main sources of anthropogenic air pollution.
- When fossil fuels burn, nitrogen oxides are released into the atmosphere, contributing to the formation of smog and acid rain. The most common nitrogen compounds released into the atmosphere by human activities are collectively called nitrogen oxides.

Burning of fossils fuels like petrol, and diesel causes:
The correct option is a)Global warming.
- Fossil fuels are formed by the decomposition of buried carbon-based organisms that died millions of years ago.
- They create carbon-rich deposits that are decomposed and burned for energy. They are non-renewable and currently provide about 80% of the world's energy.
- They are also used in the production of plastics, steel and various products. Fossil fuels include his three types: coal, oil and gas.
- When fossil fuels burn, large amounts of carbon dioxide, a greenhouse gas, are released into the atmosphere. Greenhouse gases trap heat in the atmosphere, causing global warming.
- The average global temperature has already increased by 1°C. Temperatures above 1.5°C increase the risk of sea level rise, extreme weather conditions, biodiversity loss, species extinction, food insecurity, and worsening health and poverty for millions of people worldwide. .
