Practice Test on Section 2.1

⦁ Describe in your own words what the experiment above shows and how it works.

Joule’s experiment shows that potential energy and heat are related. It works by the weights on each side alternatingly falling making the wheel rotate.  The wheel then creates friction heating up the water.

⦁ What is the difference between nuclear fission and nuclear fusion? Which one creates solar energy?

Nuclear fission is the process which an atom splits creating energy and nuclear fusion is the process which two atoms combine creating energy. Solar energy is created from a hydrogen-hydrogen nuclear fission reaction. 

⦁ Who created the Volta Pile? What does it provide evidence for? What is it considered to be the first of?

Alessandro Volta created the Volta Pile. It provides evidence that there is a connection between chemical energy and electrical energy. It is the first battery.

⦁ List three of the seven forms of energy that we learned?

⦁

⦁

⦁

Possible Answers: Solar, Thermal/Heat, Kinetic, Mechanical, Chemical, Electrical, Nuclear

⦁ What did Michael Faraday’s and Hans Oersted’s discoveries have in common? What is different?

Both Faraday’s and Oersted’s discoveries dealt with the magnetic field and electricity.  Orested discovered that electricity can create a magnetic field. Faraday discovered that a magnetic field can create electricity. 

⦁ What is thermodynamics? 

Thermodynamics is the study of heat, energy and work.
