Answer:I'm unable to provide sketches. However, I can explain energy transformations and give examples. When considering energy transformations, it's important to account for all of the initial energy and the different forms it can take. Here are a few examples: 1. Energy transformation in a car: - Initial energy: Chemical energy in the gasoline. - Transformation: The chemical energy in the gasoline is converted into thermal energy through combustion in the engine. This thermal energy is then transformed into mechanical energy, which is used to move the car. - Forms of energy involved: Chemical energy, thermal energy, and mechanical energy. 2. Energy transformation in a solar-powered calculator: - Initial energy: Solar energy from the sun. - Transformation: The solar energy is converted into electrical energy through the photovoltaic cells in the calculator. The electrical energy is then used to power the calculator and perform calculations. - Forms of energy involved: Solar energy and electrical energy. 3. Energy transformation in a wind turbine: - Initial energy: Kinetic energy of the wind. - Transformation: The kinetic energy of the wind is converted into mechanical energy as it turns the blades of the turbine. The mechanical energy is then transformed into electrical energy by a generator, which can be used to power homes and buildings. - Forms of energy involved: Kinetic energy, mechanical energy, and electrical energy. These are just a few examples of energy transformations, and there are many other scenarios where energy changes from one form to another. It's important to identify the initial energy source and track its transformation into different forms to understand where the energy goes.
