I had objects that I had to find the source energy then what it was converted to.
Please check my answers:
battery Powered Drill
chemical--> mechanical and thermal
Lava Lamp
Electrical--> thermal and nuclear
Great effort! Let's check your answers:
1. Battery Powered Drill:
To determine the source energy and its conversions for a battery-powered drill, we start by identifying the initial source of energy. In this case, it is the chemical energy stored in the battery.
Then, we consider the conversions that take place when the drill is in use. When the drill is turned on, the chemical energy in the battery is converted into mechanical energy, which is used to rotate the drill bit and perform the drilling action. Additionally, some of the chemical energy is also converted into thermal energy due to friction and heat generated during the drilling process.
So, the correct answer is:
Battery Powered Drill:
Source Energy: Chemical
Conversions: Chemical energy → Mechanical energy (rotation of the drill bit) and Thermal energy (heat generated during drilling)
2. Lava Lamp:
For the lava lamp, the source energy is electrical energy, which is supplied to it from an electrical outlet.
Regarding the conversions, when the lava lamp is turned on, the electrical energy is converted primarily into thermal energy. The lamp's heating element heats up the liquid wax inside, causing it to rise and fall, creating the lamp's signature visual effect. The thermal energy is responsible for this phase change and the motion of the wax in the lamp.
However, there is no nuclear energy involved in the operation of a typical lava lamp. Nuclear energy typically refers to the energy generated by nuclear reactions, such as those that occur within the core of a nuclear power plant or in atomic bombs.
So, the correction to your answer is:
Lava Lamp:
Source Energy: Electrical
Conversions: Electrical energy → Thermal energy
Keep up the good work!
