energy constantly changes from one form to another, but the total amount of energy in a closed system always remains the same. this concept is known formally as the law of conservation of energy. the energy conversion in a system gizmo allows you to observe the law of conservation of energy in action. in the gizmo, a suspended cylinder has gravitational potential energy. when the cylinder is released, the gravitational potential energy is converted into kinetic energy, which causes the stirrer in the water to spin. 1. what is the initial temperature (t) of the water? 25 celsius 2. click play (). what happens as the cylinder drops? the temperature in increasing as the cylinder is dropping. 3. what is the final temperature of the water? 29.69 celsius 4. why do you think the temperature of the water increased?
