Topic: The given graph shows the nitrogen oxide emissions produced by four vehicles. Summarize the information by selecting and reporting the main features and make comparisons where relevant.
Band 6.5 Answer
The accompanying line graph shows how nitrogen oxide emissions are produced. By the four different types of vehicles (diesel cars, gasoline cars, trucks, and buses).
Overall, it is evident from the graph that diesel cars create the least nitrogen oxide emissions, with buses producing the greatest levels.
The line graph shows that buses emit 40 g/km of emissions when traveling at a speed of 10 kph. However, after that, nitrogen oxide emissions began to steadily decrease to about 25 g/km at a speed of 60 kph. After then, it began to steadily grow, reaching a peak of little over 42 g/km at a speed of 130 kph. At 10 kph, lorries produce just about 35 g/km, which gradually declines to a fifth (20) g/km at 80 kph. Then it will increase slightly to 25 g/km at 130 kph.
The graph shows the nitrogen oxide emissions from diesel, gasoline, lorries, and buses. At 10 kph, buses produced 40 g/km of nitrogen oxide; at 60 kph, that amount dropped to 30 g/km. And at 130 kph, the highest amount of nitrogen oxide was emitted, at 45 g/km. The emissions from trucks are 35 g/km at 10 kph. But they can be as low as 17 g/km as the speed increases. As lorries increase in speed, their emissions rise to 25 g/km.
Nitrogen oxide emissions for diesel vehicles are used at the slowest speed. At 10 kph, the minority 5 g/km is produced, and it remains stable up to a top speed of 130 kph. The gasoline car finally produced 10 g/km at 10 kph and stayed at that level until 110 kph. But after that it began to progressively increase and produced 12 g/km at 130 kph.
Band 7 Answer
In the line graph, nitrogen oxide emissions from several vehicle types moving at various speeds are contrasted. Data calibration is done using grams per kilometer. It is evident that diesel cars generally emit the fewest emissions. Buses. However, it created the most pollutants at a variety of speeds. When traveling at 10 km/h, a diesel car initially created 7g of nitrous oxide each kilometer. At speeds over 50 km/h, the emission level remained 5 g/km despite a little decrease as the speed climbed.
The gasoline vehicle had higher nitrogen oxide emissions. At a speed of 10 km/h, it produced barely 10g of nitrogen oxide per kilometer. As the speed increased, the emissions reduced dramatically, averaging 9g/km at 80 km/h. It's noteworthy to observe that at speeds over 110 km/h, nitrogen oxide generation accelerated. On the other hand, buses and lorries produce dramatically different amounts of nitrogen oxide at different speeds. When traveling at 90 km/h, the emission level for lorries dropped to 17 km/h (17 g/km), having peaked at 10 km/h (33 g/km).
But when the speed increases, they can be as low as 17 g/km. When trucks travel at a higher pace, their emissions reach 25 g/km.
Diesel vehicles are driven at the slowest possible pace to reduce nitrogen oxide emissions. The minorities 5 g/km are produced at 10 kph, and they are stable up to a high speed of 130 kph. The gasoline vehicle's final emissions were 10 g/km at 10 kph and remained there until 110 kph. However, it then started to gradually increase and produced 12 g/km at 130 kph. The graph displays the nitrogen oxide emissions from buses, diesel vehicles, and cars. Buses produced 40 g/km of nitrogen oxide at 10 kph; at 60 kph, that quantity fell to 30 g/km. The most nitrogen oxide was released, at a rate of 45 g/km, at 130 kph. At 10 kph, truck emissions are 35 g/km.
Band 8 Answer
The nitrogen oxide emissions from several vehicle types traveling at various speeds are contrasted in the line graph. Grams per km are used to calibrate data. In general, it is clear that diesel vehicles produce the least amount of pollutants. Whereas buses produced the maximum amount/quantity of emissions at varied speeds. Initially, a diesel car produced 7g of nitrous oxide per kilometer at a speed of 10 km/h. As the speed increased, the emission level reduced somewhat, remaining 5g/km at speeds greater than 50 km/h.
Nitrogen oxide emissions were higher from the gasoline vehicle. It created little more than 10g of nitrogen oxide per kilometer at a speed of 10 km/h. The amount of emissions decreased significantly as the speed climbed, reaching an average of 9g/km at 80 km/h. It's interesting to note that the rate of nitrogen oxide production increased at speeds exceeding 110 km/h. On the other hand, the amount of nitrogen oxide produced at various speeds varies significantly in the case of buses and lorries. For lorries, the emission level peaked at 10 km/h (33 g/km) and fell to 17 km/h (17 g/km) at 90 km/h.
Once again, the rate of emissions rose over 90 km/h, peaking at 5 g/km at 130 km/h. The majority of pollution comes from buses. They generated 40g/km of nitrogen oxide at a speed of 10 km/h. At a speed of 60 km/h, emissions were at their lowest (6 g/km). And they sharply rose at higher speeds. Buses were emitting up to 43g/km of nitrogen oxide at 130 km/h.
Both the petrol and diesel car trends are remarkably similar. Similar to this, a gasoline car's emissions began at 10 g/km at 10 kph and increased as the speed increased. While a diesel car emitted more than 5 g/km at 10 kph, as the speed increased, the emissions dropped to 5 g/km before remaining stable until the conclusion.
