d2.7 compare and contrast the input energy, useful output energy, and per cent efficiency
of selected energy generation methods
(e.g., hydroelectric, thermal, geothermal, nuclear fission, nuclear fusion, wind, solar) [AI, C]
d2.8 investigate the relationship between the con- cepts of conservation of mass and conservation of energy, and solve problems using the mass– energy equivalence [PR, AI]
d2.9 conduct an inquiry to determine the specific heat capacity of a single substance (e.g., alum- inum, iron, brass) and of two substances when they are mixed together (e.g., the heat lost by a sample of hot water and the heat gained by a sample of cold water when the two samples are mixed together) [PR]
d2.10 solve problems involving changes in tem- perature and changes of state, using algebraic equations (e.g., Q = mcΔT, Q = mLf , Q = mLv ) [AI, C]
d2.11 draw and analyse heating and cooling curves that show temperature changes and changes of state for various substances [AI, C]
D. Understanding Basic Concepts
By the end of this course, students will:
d3.1 describe a variety of energy transfers and transformations, and explain them using the law of conservation of energy
d3.2 explain the concepts of and interrelationships between energy, work, and power, and identify and describe their related units
d3.3 explain the following concepts, giving examples of each, and identify their related
units: thermal energy, kinetic energy, gravitational potential energy, heat, specific heat capacity, spe- cific latent heat, power, and efficiency
d3.4 identify, qualitatively, the relationship between efficiency and thermal energy transfer
d3.5 describe, with reference to force and dis- placement along the line of force, the conditions that are required for work to be done
d3.6 describe and compare nuclear fission and nuclear fusion
d3.7 explain, using the kinetic molecular theory, the energy transfer that occurs during changes of state
d3.8 distinguish between and provide examples of conduction, convection, and radiation
d3.9 identify and describe the structure of com- mon nuclear isotopes (e.g., hydrogen, deuterium, tritium)
d3.10 compare the characteristics of (e.g., mass, charge, speed, penetrating power, ionizing abil- ity) and safety precautions related to alpha particles, beta particles, and gamma rays
d3.11 explain radioactive half-life for a given radioisotope, and describe its applications and their consequences
d3.12 explain the energy transformations that occur within a nuclear power plant, with refer- ence to the laws of thermodynamics (e.g., nuclear fission results in the liberation of en- ergy, which is converted into thermal energy; the thermal energy is converted into electrical energy and waste heat, using a steam turbine)
