This storyboard does not have a description.
How do engines and refrigerators use energy to do work?
Explain how engines use energy to do work.
Engines convert one form of energy into other useful forms and refrigerators absorb and release energy.
How do engines and refrigerators demonstrate the law of conservation of energy?
Engines demonstrate it by changing different forms of energy into another, and refrigerators store kinetic energy as potential- thermal energy.
If you done answering the question, give me the paper and leave the classroom.
One day, Jimmy and myself had to answer some questions about engines and refrigerators. The first question asks how engines and refrigerators use energy to do work.
The second question asks how engines and refrigerators demonstrate the law of conservation of energy through the transfer of thermal, kinetic and potential energy.
Since we answered all the questions, the teacher told me and my partner to go back to the classroom. When we got back to the classroom, the teacher told us to give us the paper.
