This quiz is due Sunday evening at 9 PM. No exceptions. You may use your book and outside, non-living resources. This means it should be done alone. Spelling counts.

• 1.

### Of gasoline, wood, natural gas, and coal, it is the one that has the highest energy content per gram.

• A.

Gasoline

• B.

Wood

• C.

Natural gas

• D.

Coal

C. Natural gas
Explanation
Natural gas has the highest energy content per gram among gasoline, wood, natural gas, and coal. This is because natural gas is primarily composed of methane, which has a higher energy content compared to the other substances. When burned, natural gas releases a large amount of heat energy, making it a highly efficient fuel source.

### What is the total efficiency of the fossil fuel conversion from coal to electricity in terms of percentage?

35
35%
35 percent
Explanation
The total efficiency of the fossil fuel conversion from coal to electricity is 35%, 35 percent, or simply 35. This means that out of the total energy contained in the coal, only 35% is converted into electricity, while the remaining energy is lost as waste heat.

### The device used to create electricity from wind is called a ______________.

turbine
wind turbine
Explanation
A turbine is a device that converts the kinetic energy of a moving fluid (such as air) into mechanical energy. In the context of creating electricity from wind, a wind turbine specifically refers to a turbine that is designed to harness the power of the wind and convert it into electrical energy. Therefore, both "turbine" and "wind turbine" are correct answers to the question.

### The process of creating an electric current by adjusting a magnetic field is called _______________.

electromagnetic induction
Explanation
Electromagnetic induction refers to the process of generating an electric current by changing the magnetic field strength or by moving a conductor through a magnetic field. This phenomenon was first discovered by Michael Faraday in the 19th century and is the fundamental principle behind the operation of generators and transformers. The changing magnetic field induces an electric field, which in turn causes the movement of electrons and the creation of an electric current.

### I plug my kindle touch into the wall to charge it. The type of current coming from the outlet is direct current, or DC.

• A.

True

• B.

False

B. False
Explanation
The explanation for the answer being False is that the type of current coming from the outlet is alternating current, or AC, not direct current.

• 8.

### The main components needed in electricity production are relative spinning of a wire in a ____________________.

magnetic field
Explanation
In order to generate electricity, one of the main components required is the relative spinning of a wire in a magnetic field. This is because when a wire moves through a magnetic field, it induces an electric current in the wire due to electromagnetic induction. This current can then be used to power electrical devices. Therefore, the presence of a magnetic field is essential for the production of electricity.
