because old - style light bulbs work by passing an electric current through a thin piece of metal (tungsten is commonly used in these) to heat it up enough to make it glow. In these old - fashioned light bulbs, most of the input energy is given out as heat (about 95%) and the rest light. However, in new, so called,"energy efficient" light bulbs, an electric current is passed through different gases (including Mercury gas) to make the particles collide with each - other and give out light. Depending what metal vapour you use determines the colour of the light given off. These are more energy efficient because about 60% of the energy given out is heat, and 40% light, so it isn't ideal, but is better than the old light bulbs. However, these new light bulbs might not be entirely benefitial as they are less cost - effective than the old ones. Written by a 12 - year old!
What else can I help you with?
What energy transformation is ins flashlight?
A flashlight transforms electrical energy from batteries into light energy and heat energy.
When a flashlight is turned on where does the energy transformation takes places?
The energy transformation in a flashlight occurs inside the bulb when electricity is converted into light and heat energy. The battery provides electrical energy to power the light bulb, which then produces light and heat as a result.
What is the energy transformation for a flashlight?
chemical to light :)
What are the energy transfers that occur in a flashlight?
In a flashlight, electrical energy from the battery is converted into light energy and heat energy in the bulb. The battery provides the electrical energy, which powers the light bulb to produce both light and heat.
When the flashlight is turned on what energy changes?
When a flashlight is turned on, electrical energy from the battery is converted into light energy and heat energy by the bulb. The chemical energy stored in the battery is transformed into electrical energy, and then into light and heat energy by the bulb to produce the illumination.
When the flashlight is turned on electrical energy is is changed to which type of energy?
When a flashlight is turned on, electrical energy is converted into light energy and heat energy. The electrical energy powers the bulb to produce light, while some electricity is lost as heat.
What is the energy transformation of a flatshlight?
A flashlight transforms electrical energy into light energy and some heat energy. When the battery powers the flashlight, the electrical energy is converted into light energy when the bulb or LED emits light, while some of the energy is also lost as heat.
What form of energy is given off by a flashlight?
A flashlight is given off light and heat energy once turn on.
What energy transformation occurs when you turn on a flashlight?
When you turn on a flashlight, electrical energy from the battery is converted into light energy and a small amount of heat energy by the light bulb.
What energy transformation takes place when you use a flashlight?
In a flashlight, electrical energy from the battery powers the light bulb, which then converts electrical energy into light energy and heat energy.
Energy transformation occurs when a flashlight shines?
When a flashlight shines, electrical energy from the battery is transformed into light energy and heat energy. The electrical energy powers the bulb, which then emits light energy and some heat energy as a byproduct of the process.
How does the amount of energy in batteries in a flashlight compare to the total amount of energy given off byt the flashlight as light and heat?
All of the energy in the battery, or most of it, is eventually given off as heat and light.
