Energy Assignment (30 pts.) Module 1, Unit 1.1 - Energy Assignment - 30 points 1. Why is energy not as tangible (concrete, certain, definite, plainly knowledgeable) to us as matter? (2 marks) Energy is an ability and so it is not as tangible as matter. We cannot see it with the naked eye and energy comes in different forms that can be converted from one to another. These properties make energy not as tangible. 2. List four forms of energy and an example for each form. To get the eight marks for this question, you need to list four forms of energy and four examples (one example for each form of energy). (8 marks) Mechanical energy- lever, electric motor, solar sail, muscle Thermal energy- brakes, heat exchanger, solar collector Electric energy- transformer, solar cell, fuel cell, beta radiation Chemical energy - fire, photosynthesis, radioactive decay 3. What is the First Law of Thermodynamics? (2 marks) Energy cannot be created or destroyed but only converted to other forms – and - heat is a form of energy.
