1. Which of the following best describes the Law of Conservation of Energy?
Energy can be created but not destroyed.
Energy can be destroyed but not created.
Energy can be converted from one form to another, but the total amount remains constant.
Energy is always lost during conversion.
2. In a hydroelectric power plant, which energy conversion sequence occurs?
Electrical → Mechanical → Potential
Kinetic → Potential → Electrical
Potential → Kinetic → Electrical
Thermal → Mechanical → Electrical
3. The efficiency of an energy conversion process is defined as the ratio of energy to energy.
4. A solar panel converts energy into energy.
5. Explain the concept of 'energy degradation' and how it relates to the Second Law of Thermodynamics.
6. Describe two different types of energy conversion that occur within a car engine.
7. All energy conversion processes are 100% efficient.
True
False
8. Chemical energy is a form of potential energy.
True
False
9. Consider the energy conversions that occur when a person eats food, then rides a bicycle up a hill. Trace the main energy transformations from the food to the kinetic and potential energy of the cyclist and bicycle. Mention any energy losses.
