Gizmo: Energy Conversions in a System Gizmo – Graded A+ M11L3A Energy Conversions in a System Gizmo 2020 Student Exploration: Energy Conversion in a System 1. What are some examples of devices that are powered by batteries? Car, calculator, phones, refrigerator 2. What different forms of energy are demonstrated by these devices? Kinetic or electrical energy 1. What is the initial temperature (T) of the water? 25C 2. Click Play (). What happens as the cylinder drops? Temperature increases, and the cylinder decreases in height as it lowers from its original position in the air 3. What is the final temperature of the water? 29.6 4. Why do you think the temperature of the water increased? The movement of the turbine fan in the beaker transferred more kinetic energy adding hear energy to the water itself Question: How does the cylinder’s initial height affect its gravitational potential energy? 1. Predict: How do you think increasing the cylinder’s height will affect the final temperature of the water? Increasing the cylinders height will affect the final temperature of the water because the higher the cylinder is the harder it will fall hence producing more heat than what it was in a lower height Gather data: Make sure the water’s Mass is 1.0 kg, its Temp is 25 °C, and the cylinder’s Mass is 5 kg. Set the cylinder’s Height to 100 m. (Note: The large height scale used by the Gizmo, while not practical in a real-world experiment, makes it easier to produce observable temperature changes in the water.) Click Play, and record the water’s final temperature in the table
