The graph below compares the total amounts of greenhouse gas emissions expected for future mid-size cars, including emissions th
at occur when moving fuels from their original source to fueling stations where people can buy the fuels for their cars. Amounts are shown in
grams of CO2 (or equivalent greenhouse gas) per mile driven by the mid-size car.
Which vehicles are the best choices for environmentally friendly cars?
A. Fuel cell Electric and battery electric
B. Hybrid electric and plug-in hybrid electric
C. Conventional internal combustion and hybrid electric
D. Conventional internal combustion and battery electric
Explanation: Groundwater can cause erosion under the surface as it moves through the soil. During the movement an acid is formed which what causes erosion and deposition.
It is important to use low flame when evaporating water from a recovered filtrate because then the water and filtrate will not spatter and the filtrate can also be recovered after evaporating water.
If flame is not low then water as well as got spatter so it is important to use low flame so that the water and filtrate will not spatter.
