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.
The control group gives you something to compare the results to.
Planck's constant.
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.
the plants will die because heat gives energy to all plants and that is how plants make there own food
The sun gives energy, in the form of heat and light.
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.
From chemical to heat and light. Batteries are chemical energy, the bulb emits lights but also gives out heat.
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.
The batteries in the flashlight store chemical energy. Once you turn the flashlight on, this chemical is converted into light and heat energy.
a flashlight using chemical and gives out electromagentic enery and a little bit of thermal
it doesn't save it, it just gives energy to what you use it for... so the answer is no
Yes because the acid inside the battery gives it power.
it gives you more energy than other foods
it gives you more energy than other foods
the lightbulb is connected to the batteries, and the lightbulb gives off energy in the form of photons (light).
the sun gives energy also any sort of living organism always tranfers some sort of energy ... like the patatoes you see making a light bulb illuminate.
a part of the energy that is transferred to the load is lost in heating.Therefore actual work done by the charge will be a little less.
