It becomes heat. You can feel it at the top of the TV set. All wasted energy is eventually converted to heat.

What kind of energy does a hair dryer use?
Electrical energy enters the hair dryer and is converted into kinrtic energy as a smallelectric motor spins a fan blade. Electrical enrgy is also converted into thermal energy in a grid of wires that heat up. The fan forces air across the hot wires , and hot air blows out of the nozzle of the hair dryer. You can hear the sound energy that comes out. In other words in is converted from Electrical energy -to- Kinetic energy and, Electrical energy -to- Thermal energy and, last but not least, Sound energy!
What is input energy?
Where the energy enters the system.
What is the energy transformation that takes place in a television?
Simple answer: Electrical energy comes in and heat, light and sound energy goes out. There are two input sources, the electromagnetic signal that is the actual information of what is to be displayed and there is also the electric power provided to operate the television. Typically, the power comes from an electrical cord plugged into the electrical outlet on the wall and the signal is a cable from an outside source or an antenna. The input energy is electrical energy to power the TV and the signal is electromagnetic energy. The output of primary interest is the image on the screen which is light energy, so the television puts out light energy which is also electromagnetic energy. The television may also produce sound, in which case there is sound energy put out. In the process of making light and sound, the components of the television heat, so heat energy is put out. Summary: Input: Electrical energy enters in two forms, electromagnetic signal and electricity. The electricity is the far greater source of energy. The energy in the signal is tiny. Output: Heat, light and sound exit the television. Heat is the largest and in excess of 90%. Sound energy will be substantially greater than the amount of energy contained in the light.
What happens to the other 90 percent of energy and in what form does it re-enter the environment?
When energy is passes between tiers only ten percent of the energy is passed on. The other 90 percent is used by the previous organism and it re-enters the environment from the sun.
What kind of energy is invloved in hearing and vision?
When a sound is produced, it is carried as vibrations through the air. these vibrations enter the ear and make the ear drum vibrate. This is kinetic energy. The inner ear converts this kinetic energy into electrical energy, which travels along the nerves to the brain. Light enters the eye as electro-magnetic energy. This energy is converted by the retina first into chemical energy, which is then converted to electrical energy in the nerves as the signal travel to the brain. Where nerves join other nerves, the signal has to jump across a gap called a synapse. This is done by converting the energy back into chemical energy, the chemical energy travels across the synapse and is converted back into electrical energy. In short: Ears - Kinetic, electrical and chemical Eyes - Electromagnetic (light), electrical and chemical
Describe a case in which electrical energy is converted into thermal energy?
hair dryer, electrical energy enters the hair dryer and is converted to kinetic energy as a small motor spins a fan blade the electrical energy is converted to thermal by a grind of wires that heat up
What happens when a space shuttle enters the atmosphere?
energy is lost
Describe what happens to radiant energy once it enters the atmosphere?
It may be converted into heat (or cause chemical reactions to occur), otherwise it remains radiant energy and escapes back into space. Note that much of what stays as heat is converted back into infra-red radiation and lost into space at night.
What happens to solar energy as it enters earths atmosphere?
it gets absorbed by the ground
What happens to glucose after it enters the cell?
There are three main uses of the glucose made by photosynthesis:1) It can be used as a source of energy (in respiration)2) It can be converted into starch and stored3) It can be converted into other substances eg cellulose, fats, proteins etc.
What happens if too much energy from the sun enters Earth's atmosphere?
The earth will become warmer.

How does energy from the sun enters the atmosphere?
The energy from the sun enters the atmsphere as radiation. This radiation is tranmited to the earth in the form of short waves of radiation. These waves hit the ground.Through radiation.
What happens when a computer saves an image of the desktop and enters a state of reduced power consumption to save energy?
Hibernation
