Energy Transformations and Heat Pollution

Which type of power plant relies on a renewable form of energy to create electricity?
1. Hydroelectric
2. Coal
3. Natural gas
4. Nuclear
What is an advantage of using nuclear energy to produce electricity?
1. No air pollution
2. Heated waste water
3. Nuclear waste
4. Risk of a melt down
In most energy transformations, the end result is the production of
1. heat.
2. matter.
3. gases.
4. nuclear waste.
The easiest way to cool down a factory is to release hot air directly from the building into the environment. What is not a typical cooling method?
1. Blast furnaces
2. Large fans
3. Cool water circulation
4. Air conditioning system
Which statement about heat pollution is false?
1. Adding heat to a water system can increase oxygen to dangerous levels
2. Living things are very sensitive to changes in temperature
3. If added heat has a negative effect on an ecosystem, it is a form of pollution
4. Factories are a major source of heat added to ecosystems
Which statement about the effect of human activities on the environment is false?
1. Human activities have created all the greenhouse gases that exist in the atmosphere
2. Human activities produce heat that ends up in the environment
3. Human activities consume energy, some of which ends up as heat released into the environment
4. Human activities increase the amount of greenhouse gases in the atmosphere
Which statement is an argument for using coal as a source of energy?
1. Coal is relatively cheap and plentiful, and easy to access from our environment
2. Coal is a renewable energy source so it will potentially last forever
3. Coal can be crushed to release its energy so it does not contribute any greenhouse gases
4. Coal mining does damage to the ecosystem where it is carried out
What is an example of heat pollution?
1. The Arctic Ocean is losing its ice floes as it warms, and polar bears are now endangered because they cannot hunt for seals in open water
2. Cold boreal forests are experiencing warmer winters and many wild birds are extending their ranges in this zone
3. Farmers in Central Ontario can now grow warmer season crops because the growing season has been extended due to global warming
4. Some corals are changing the type of symbiotic algae they contain, allowing them to adapt to rising seawater temperatures caused by global warming
Which of the following statements about energy conversion is false?
1. All energy converters create greenhouse gases as a byproduct
2. Energy conversion generally creates heat
3. Power plants are basically large energy converters
4. Any powered device or appliance is an energy converter
Why is nuclear waste a problem, when considering nuclear energy as an energy source?
1. Nuclear plants create a waste product that must be carefully stored for a very long time
2. Nuclear plants can potentially create an enormous amount of energy
3. Nuclear plants rely on a very limited raw energy source, uranium, which is in short supply
4. Nuclear plants must convert radioactive energy into heat in order to be useful, and this creates greenhouse gases
