What kind of energy given out by light bulbs and candles?
Light bulbs give out light and heat energy, while candles give out light and heat energy through a chemical reaction between the wax and a wick.
What are several sources of light energy?
The sun, light bulbs, candles, and LED lights are all sources of light energy.
How do candles save energy?
Candles can save energy by providing a source of light without the need for electricity. By using candles instead of electric lights, energy consumption is reduced. However, using candles may not be a practical or cost-effective way to save energy on a large scale.
What two energy changes happen in a light bulb?
In a light bulb, electrical energy is converted into radiant energy (light) and thermal energy (heat). When the bulb is turned on, the electrical energy flowing through the filament heats it up, causing it to emit light while also generating heat as a byproduct.
Where can light and sound energy be found?
Light energy can be found in sources such as the sun, light bulbs, and candles. Sound energy is produced by vibrating objects such as musical instruments, human voices, and machinery.

What is normal energy consumption of electric candles?
Electric candles are powered mostly by Light Emitting Diodes(LEDs). These electric candles have a normal energy consumption rate of between 3 and 5 Watts.

How is candles a form of chemical energy?
Candles rely on chemical energy stored in the wax. When the candle is lit, the wax undergoes a chemical reaction with oxygen in the air to produce heat, light, carbon dioxide, and water vapor. This process releases the chemical potential energy stored in the wax as heat and light energy.
When energy changes from sound to light what happens to the energy?
It changes to another form.
Where can light and sound energy be found?
Light energy can be found in sources such as the sun, light bulbs, and candles. Sound energy is produced by vibrating objects such as musical instruments, human voices, and machinery.
What are some ways that energy changes form in a car?
It changes electrical energy to thermal energy and light energy
What energy changes are involved when an electric light shines?
When an electric light shines, electrical energy is converted into light energy and heat energy. The electrical energy is converted into light energy, which is the main purpose of the light bulb, while some of the energy is also released as heat energy due to the resistance in the light bulb filament.
Do burning candles use energy?
More accurately, burning candles convert energy from one form to another. The chemical energy available in the wax of the candle is converted, through the chemical reaction of burning, into primarily light and heat.
Which energy changes light energy into electrical energy?
Different light bulbs, lamps, flashlights, LEDs.
