Coal is a __________ energy resource.
Renewable
Non-renewable
Which type of energy is not involved in a coal power station?
Chemical
Thermal
Electrical
Solar
Bioethanol is produced from
fermentation of sugars
the breakdown of organic waste
fatty acids and methanol
fatty acids and methane
Which of the following is not renewable energy?
Wind energy
Biofuels
Natural gas
Solar energy
Sustainability is about meeting the long-term ongoing needs of society, as well as immediate and short-term demands.
True
False
Non-renewable energy are resources which are used up more quickly than they can be replaced. Examples: Fossil fuels (coal, crude oil, natural gas, coal seam gas) and uranium.
True
False
All fossil fuels generate CO2 when combusted.
True
False
Which of the following about fossil fuel is NOT correct?
Non-renewable and finite
Contains trace sulfur, nitrogen that will form SO2 and NO2 during combustion reaction, which causes acid rain
Coal has the least environment problem among all fossil fuels
Mining coal destroys land
Coal with higher percentage of carbon and lower percentage of water has higher heat of combustion.
True
False
Crude oil or petroleum, is a liquid mixture of hydrocarbons that are mostly members of the homologous series of alkanes. It is formed from dead marine organisms (plants and animals) millions of years ago.
True
False
Using fracking method to mine natural gas may pollute underground water supplies.
True
False
Biofuels are sourced from biomass (living, or recently living biological material), including plant materials and animal waste, and are renewable fuels. The main biofuels are biogas, bioethanol and biodiesel.
True
False
Production of bioethanol has two stages:
1st Stage: breakdown of starch and sugar in plant material (such as barley, wheat, corn and potato) to produce glucose using anaerobic bacteria.
2nd Stage: the fermentation of glucose to form ethanol.
True
False
Biogas is pure methane
True
False
Which of the following is NOT the general advantage of biofuel?
Renewable, can be replenished within relative short time
Less net carbon emissions
Is carbon neutral
Depending on the source, may generate less SO2 during combustion.
Choose the INCORRECT statement about the use of bioethanol as a fuel
Produces carbon dioxide as a product when combusted
It can be considered as carbon neutral
The glucose fermented to produce the ethanol can come from sugar cane waste
It is a renewable fuel source
Checkpoints P1Q1: Which of the following statements about fuels is correct?
When fuels react they all produce carbon dioxide
Heat energy is always released when fuels are burned.
All fuels are hydrocarbons.
Fuels need pure oxygen to produce energy.
Checkpoints P1Q2: Which one of the following lists contains only fossil fuels?
Biogas, bioethanol, biodiesel
Coal seam gas, biogas, natural gas
Coal, petrol, diesel
Peat, wood, charcoal
Checkpoints P2Q7: The following is a list of fuels: 1) Coal-seam gas; 2) Biogas; 3) Natural gas; 4) Biodiesel; 5) Bioethanol; 6) Petrol. Which of these are renewable fuels?
2, 4, 6
2, 3, 6
1, 3, 5
2,4, 5
Checkpoints P3Q12 (VCAA 2015Q5): Which one of the following statements best defines a renewable energy resource?
An energy resource that will no be consumed within our lifetime
An energy resource that does not produce greenhouse gases when consumed
An energy resource derived from plants that are grown for the production of liquid biofuels
An energy resource that can be replaced by natural processes within a relatively short time.
Checkpoints P3Q13 (VCAA 2014 Q24): Methane gas may be obtained from a number of different sources. It is a major component of natural gas. Methane trapped in coal is called coal seam gas and can be extracted by a process known as fracking. Methane is also produced by the microbial decomposition of plant and animal materials. In addition, large reserves of methane were trapped in ice as methane hydrate in the ocean depths long ago. Methane is a renewable energy source when it is obtained from
Natural gas
Coal seam gas
methane hydrate
microbial decomposition
Checkpoints P3Q14 (VCAA 2017 Q5): Which one of the following is a biofuel
ethanol produced from crude oil
ethanol produced from cellulose
propane produced from natural gas
electricity produced by hydro-power
