Question

1. solar panel in no cloud cover with an incandescent light bulb system

in this system, ____________ energy from the sunlight causes the solar panel to create __________ energy which flows into the incandescent light bulb. in the light bulb, the __________ energy is transformed into two different types of energy: __________ energy and ____________ energy.

1. turbine moved by steam from medium heat kettle with a fan

in this system, ____________ energy from the flames of the fire transfer energy to the kettle causing the liquid to become steam. the thermal energy of the steam spins the turbine (__________ energy) which generates __________ energy that is used to operate the fan. the moving electric motor and the spinning fan blades are a form of __________ energy. after running for a while, the fan becomes hot to the touch, and ever so often releases ____________ energy into the air.

Explanation:

Question 9

1. Sunlight is a form of radiant (or solar) energy. Solar panels convert radiant/solar energy into electrical energy.
2. Incandescent light bulbs take electrical energy and convert it into light energy and thermal (heat) energy (since incandescent bulbs get hot and produce light).

1. Fire flames produce thermal (heat) energy. This thermal energy is transferred to the kettle, turning liquid to steam.
2. Steam's thermal energy spins the turbine, which is a form of mechanical energy (movement of the turbine).
3. The turbine's mechanical energy is converted into electrical energy to operate the fan.
4. The moving motor and fan blades are mechanical energy (movement).
5. When the fan gets hot, it releases thermal (heat) energy into the air.

Answer:

In this system, \(\boldsymbol{\text{radiant (or solar)}}\) energy from the sunlight causes the solar panel to create \(\boldsymbol{\text{electrical}}\) energy which flows into the incandescent light bulb. In the light bulb, the \(\boldsymbol{\text{electrical}}\) energy is transformed into two different types of energy: \(\boldsymbol{\text{light}}\) energy and \(\boldsymbol{\text{thermal (heat)}}\) energy.
