Compared to other types of light-bulb, energy-saving light bulbs will create less heat. This is because any wasted energy is converted to heat.
yes
Endothermic. Assuming the energy absorbed is heat. Exothermic reactions release heat, such as the oxidation of hydrogen to create water.
the heat chamber.
== == The invention of the lightbulb was a significant milestone in human history because it eliminated peoples' dependece on candles and oil lamps, and created an easier way to light houses at night. When the lightbulb and electricity were first invented however, it was sometimes unreliable, but as time passed and technology improved, the lightbulb changed the ways the people lived their day-to-day lives.
If there was more heat to absorb than was already in the material.
It takes more heat to boil water than to simply heat water. Unless the water is already at its boiling point.
No, solar panels do not create heat they create energy
The power rating for a light bulb (like "40 W") tells how much electrical power the light bulb uses. All of the power used by the bulb is either converted into light or heat. In an incandescent bulb, most of the energy becomes heat. In a fluorescent bulb, more of it becomes light.
When you distort something, the particles bump into each other more often, creating heat.
An incandescent bulb gives off more heat than a fluorescent bulb.
Plasma televisions require more light to create screen images, and in turn this generates more heat.
It makes thermal energy (the heat), radiant energy (what we see), which is in essence more or less the same manifestation.
They cool and heat more slowly than the land around them
They cool and heat more slowly than the land around them.
more than needed????
More than one apparently!
Heat is a form of energy and in appliances like toasters energy is transmitted into the metal of the toaster causing the heat. Resistance to the flow of the electricity through the coils of wire in the toaster create heat. ---/////--- more coils equals more heat. ---/////////////---.
No. No device creates more power than it consumes. There are always losses - friction, heat, etc. - so it is impossible to create a perpetual motion machine.
