Energy Test 2020

A city plans to use solar energy as part of a new plan to manage the city’s energy resources. What is a possible disadvantage of this plan?

• Air pollution will increase dramatically

• Solar panels are very expensive to build

• More water will be required to cool equipment

• People would never be able to use solar energy at night

Coal is a natural resource. Why is coal considered nonrenewable?

• Coal will never run out

• No new coal is being produced on Earth

• Coal is used to produce energy and not materials

• Coal is being used faster than it is being produced

Which device is designed to transform chemical energy --> electrical energy --> light (radiant) energy?

• a lamp

• A flashlight

• A radio

• A toaster

Which of the following responses best explains how fossil fuels form?

• Fossil fuels are made by human processes at a factory

• Fossil fuels form as wind and running water break down fossils

• Buried rocks are exposed to heat and pressure and slowly turn into oil, coal, or natural gas

• Buried plants and animal remains are exposed to heat and pressure and slowly turn into oil, coal, or natural gas

The diagram below shows a student heating a pot of water over a fire. The arrows represent the transfer of thermal energy.

What is the law of conservation of energy?

• The total amount of energy on Earth is constant

• Energy can only be created when a force acts on an object

• Heating an object creates energy and cooling destroys energy

• Energy cannot be created or destroyed but it can be transformed and transferred
