1. When enough HEAT is added to a substance, its state of matter will change. list the states of matter from least movement of particles to most movement of particles.

solid, liquid, gas

2. In the study of energy, OHM'S law tells us the voltage can be calculated by multiplying resistance x energy CURRENT. If 30 amperes of current are flowing through a wire that has a resistance of 4 ohms, what is the voltage of the battery in Watts? 120 WATTS

3. What are the basic fundamentals of how energy is produced through the methods of burning coal, natural gas, wind farms, and hydroelectric.

de the --> this connects to power lines which have resistance and current which makes _.

Wind/Water turn the _ --> this turns the magnet inside the --> this connects to power lines which have and _ which make _.RKO OUTTA

4. Heat is given off when an object's thermal energy is transferred. Thermal energy can be transferred in how many ways? Name, define and give an example of each..

b. heat from a solid transfers to the atmosphere is EXAMPLE

c. heat from a solid transfers to another _ is _ EXAMPLE

5. There are dozens of subcategories of energy types, but what are the two main forms of energy? Give an example of each.

Energy of movement _ EXAMPLE _

Stored energy _ EXAMPLE

6. Give the names of the 3 types of fossil fuels and explain why we continue to use them more instead of alternatives like wind or water.

7. Why do nuclear power plants use surrounding water sources? Describe the environmental associated with this.

8. Explain how electromagnets work using the terms electromagnetism, copper coils, voltage, and iron nail.
