It is never possible to totally convert heat energy into useful work true or false?

That is true. To research some more, do some reading on the "Second Law of Thermodynamics".

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.
Does an electric can opener convert electric energy sound energy?
Not likely - any machine wastes some energy; that would reduce the useful output energy.
Is the energy of carnot engine is maximum?
The work output of a Carnot engine would be the maximum possible, i.e. it would yield the maximum possible efficiency for conversion of input energy into useful work.
If electrical energy goes into a light bulb what useful energy comes out?
The useful energy that comes out is light energy. Heat energy is also produced but is not useful
The laws of thermodynamics state that whenever energy?
In any process energy is conserved, i.e. it is neither created nor destroyed; it just changes form. In any process some energy will be lost as heat; you can't convert all energy from a source into useful work.
Is it always easy to collect wasted energy and use it?
Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.
Can energy be destroyed but not created?
Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.
Is solar energy expensive to convert to a useful form?
False
Does an electric iron convert electric energy to heat and motion?
heat(useful energy) and sound(waste energy)
Can you destroy solar energy?
I am not entirely sure what you mean. As you may already have heard, energy can't be created or destroyed. However, it is possible to convert useful energy into unusable energy - in fact, this happens all the time. In a way, this will "destroy" the energy by making it less valuable.
Humans convert approximately of the energy stored in food to useful work?
40%
What type of energy does a TV convert to?
Converts Electrical energy into the useful energy, light and sound. There will be some unwanted heat energy as well
How do you convert heat into sound?
For example, if you have a lot of heat in one place, you can get an explosion, which is accompanied by a sound. Note that in general, it is only possible to extract useful energy from heat if there is a temperature difference.
Why is electrical energy is useful?
electricity can be useful in alot of things. You will not imagine how much you use electricity throughout the day. You mostly use it for light. right now you are using electricity while you are reading this. You use it when your watching TV, or playing video games, or using an air conditioning machine. that is how electricity is useful.
How can energy be lost from a food web?
Total energy is always constant; however, on the other hand, it is possible to convert useful energy into useless energy. This is an irreversible process, so for all practical purposes, this energy is "lost". It still exists as some type of energy (usually heat), but it can no longer be used.
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.
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.
