Is solar energy expensive to convert to a useful form?
False
Where does the energy in an energy pyramid come from?
The sun and then the primary producers which are able to convert the energy from the sun into a form that can be used to the rest of the creatures on the energy pyramid
Why do engines get hot?
The energy produced by the engine is mostly used to power the car, but due to an imperfect design, some energy still remains in the form of heat.
What do you need to get energy?
You cannot create energy. You can simply convert energy from one form to another, for example potential energy to kinetic energy - dropping a ball, when the ball is released it has potential energy which is converted into kinetic energy as it falls (plus some heat energy). The total energy of a system has to remain constant, this principle, the conservation of energy, was first postulated in the early 19th century, and applies to any isolated system.
Whether water is good fuel or not?
Water is an excellent fuel for internal combustion engine, But, It takes A LOT! of energy to make it to the form to burn
Is solar energy expensive to convert to a useful form?
False
What does harness means referring to energy?
It means to convert the energy to a form that is useful for humans - for making machines work, for example. Or simply, convert to a form of energy that is easily converted to other forms of energy, for example, AC electricity, at an appropriate voltage.
Why you convert chemical energy into mechanical energy?
Chemical energy in its form is not very useful. Thus to use it better and more efficiently, it is converted to mechanical energy.
Why is heat energy is the least energy?
Least what? Anyway, heat energy is in a way the least useful form of energy, because you can normally convert any other energy to heat energy, but if you have heat energy, you can no longer convert all of it back to other forms of energy.
Is it true fossil fuel's transform chemical energy into another form of energy?
If you mean the use of fossil fuels, yes. Typically, the fuels are burned (for example, in a car engine), converting the chemical energy into heat. Part of this is then converted into movement. A heat engine can only convert part of the heat energy into useful energy, so the remainder is wasted.
Can energy be destoyed?
No. However, you can (and will) convert high-value energy to low-value energy. In other words, energy gets "used up" in the sense that it gets converted into a form that is no longer useful.
What form of energy is not useful from a computer?
heat energy
Why sunlight is not an useful form of energy?
Actually it is - very useful.
Is gold useful in energy production?
Currently, gold is not useful in any form of energy production.
What form of useful energy can solar energy be transformed into?
electricity
What is opitical transducer?
A device that convert one form of energy into another form is called the transducer. so optical transducer is a device that can convert electric energy into optical energy.
What are the two features of all living organisms?
All living things are made up of cells. On the cellular level they also convert biochemical energy into a form that is useful to the organism.
