How does energy from flashlight batteries compare to the light and heat the flashlight gives off?
This depends entirely on the efficiency of the lamp. Tungsten lamps tend to give off more heat than light, whereas LED technology give off more light than heat.
By the laws of thermodynamics the sum of the energy that comes out of the system must equal the sum of the energy that goes into the system.
So:
Energy in batteries = Total light energy produced + Total heat energy produced
The efficiency therefore becomes the ratio between produced light energy and heat energy.
What else can I help you with?
Why do you need to have a control group when conducting experiments?
The control group gives you something to compare the results to.
The ratio of energy to frequency for a given photon gives?
Planck's constant.
Can you compare evaporation and condensation?
Evaporation is the process in which there is a change of state from liquid to gas. Condensation it is the process in which there is a change of state from gaseous to liquid or solid. Evaporation takes place from surfaces, all the time at all places Condensation can take place on surfaces, or at any place in a gas, though it is often aided by the presence of dust or other small particles. Evaporation absorbs energy. Condensation gives out energy.
What will happen to plants if there is no heat energy?
the plants will die because heat gives energy to all plants and that is how plants make there own food
What does the sun give us here on Earth?
The sun gives energy, in the form of heat and light.
What type of energy does a flashlight give off?
A flashlight gives off light energy, which is a form of electromagnetic radiation. The light energy is created when the flashlight's batteries produce electrical energy that powers the light bulb or LED to emit light.
How can a flashlight be non-luminous?
infra red maybe??? get a remote and your camera phone and you'll see what i mean or A flshlight can be non-luminous because the batteries from the flashlight gives the energy that makes light.
What are the Examples of energy transformation from electrical energy to radian energy?
flashlight: the battery in the flashlight transforms it's chemical stored Energy into electrical Energy which is then transformed into radiant energy because of the light the flashlight gives off.
What kind of energy transformation is a flashlight?
A flashlight transforms electrical energy into light energy and a small amount of heat energy. The electrical energy powers the light bulb, which then emits light energy to illuminate its surroundings.
What energy does a flash light have It has light heat and chemical Light because that's what it gives off Heat cause when turned on it starts giving heat and chemical because the battery consists of c?
The batteries in the flashlight store chemical energy. Once you turn the flashlight on, this chemical is converted into light and heat energy.
Does a flashlight use electrical energy or thermal energy?
a flashlight using chemical and gives out electromagentic enery and a little bit of thermal
How does a flaslight work?
A flashlight works by converting electrical energy from batteries into light energy through a bulb or light-emitting diode (LED). When the switch is turned on, the circuit is completed, and the electrical current flows through the bulb or LED, causing it to emit light.
Do batteries save energy?
it doesn't save it, it just gives energy to what you use it for... so the answer is no
Would the energy in batteries be chemical energy?
Yes because the acid inside the battery gives it power.
How does the energy in an apple compare to the other foods?
it gives you more energy than other foods
How does the energy in an apple compare to the other foods listed?
it gives you more energy than other foods
What type of energye is given off by a flashlight as light and heat?
A flashlight gives off both light energy in the form of visible light and heat energy, typically in the form of infrared radiation. The light energy allows us to see in the dark, while the heat energy is a result of the energy lost in the conversion process from electrical energy to light energy.
