D Question 18 4 pts Which of the following statements about incinerators is FALSE? Incinerator emissions to the atmosphere contain toxic chemicals. O The ash from incinerators must be disposed of in a hazardous waste landfill Incinerating waste produces as much energy as burning coal. Incinerators reduce the volume of material that needs to be landfilled. D Question 19 4 pts Which of the following statements about waste incineration is FALSE? Waste incinerators are cheaper than landfills to construct and operate. Waste incineration can pollute air and water Waste incineration creates toxic ash, which must be disposed of properlyExplanation / Answer
Hi Answer:
18.Which of the following statements about incinerators id FALSE?
Answer: Option C (Incinerating waste produces a much energy as burning coal)
Explanation: The incineration process much more energy than the coal brining. The net energy produced per tonne municipal waste is about 2/3 MWh of electricity and 2 MWh of district heating. Thus, incinerating about 600 metric tons (660 short tons) per day of waste will produce about 400 MWh of electrical energy per day .
19. Which of the following statements about waste incineration is FALSE?
Answer: Option A (waste incineration are cheaper than landfills to construct and operate)
Explanation: The installation of a waste incineration plant needs a huge amount of money. Whereas landfill can be determined and accessible with a little amount.
21. Which of the following action is NOT a way to ADAPT to ongoing climate change?
Answer: Option C (move communities away from storm surge zone)
Explanation: By moving from one zone to another zone is not the solution to the climate change problem we have to reduce the carbon emission and reduce the global warming.
24. All of the following forcing factors contribute to the warning of the climate, except for which one?
Answer: Option A (Bad tropospheric ozone)
Explanation: Ozone is not directly related to the warming of the climate whereas the other factors such as sulfate aerosols, Methane, and carbon dioxide are the major cause of climate warming.
25. Which fuel has the highest energy output?
Answer: Option A (biomass biodiesel)
Explanation: Because this biofuel gives both electricity as well as biofuel i.e. ethanol or biodiesel. Hence maximum energy output and less farming as well as short fuel conversion process. Whereas in case of biomass ethanol biofuel is formed more and less electricity so efficiency will be less.
