What is the name of the non useful energy?
That would be "heat", except that sometimes heat can be quite useful.
What is gross calorific value and useful heat value of coal?
what is the differnence between gross calorific value and useful heat value
Why are fossil fuels and biomass useful sources of energy?
They both burn easily with lots of heat.
Why are fossil fuel and biomass useful as source of energy?
They both burn easily with lots of heat.
Why are infrared sensors more useful at night?
Infrared is heat and during the day other objects are hot besides bodies

When is it useful not useful to heat materials?
It is useful to heat materials when attempting to change their physical properties, such as melting or shaping. However, it may not be useful to heat materials that are sensitive to heat and may degrade or become damaged, or when temperature control is crucial for the material's stability.
What is gross calorific value and useful heat value of coal?
what is the differnence between gross calorific value and useful heat value
Can scientists construct an engine that does nothing but convert heat to useful work?
Yes - with certain limitations. You can convert part of the heat - not all of the heat - into useful work, if there is a heat difference. The remainder of the heat (from the hot container) gets passed to the cold container. You CANNOT convert ALL the heat into useful work, nor can you convert heat into useful work if there is no heat difference. All this would contradict the Second Law of Thermodynamics, and it is very unlikely that this law will ever be violated.
Were is friction useful?
When you want heat and grip.
What is the not useful energy when coal is burnt?
When coal is burnt, the energy lost in the form of heat and pollutants such as carbon dioxide and ash is considered as not useful energy. This includes waste heat that is not converted into useful work or electricity.
Energy that is not converted to useful energy is usually given off as?
heat
What form of energy is not useful from a computer?
heat energy
What is a property of aluminum that makes aluminum foil useful in baking?
Heat conduction and heat tolerance.
If electrical energy goes into a light bulb what useful energy comes out?
The useful energy that comes out of a light bulb is primarily in the form of light and heat. The electrical energy is converted into light energy that illuminates the surroundings and heat energy that warms up the light bulb and its surroundings.
Is heat energy always useful?
No, heat energy is not always useful. In some situations, like in the case of unwanted heat in electronics causing overheating, heat energy can be detrimental. However, in many cases, heat energy is harnessed for various purposes such as cooking, heating buildings, and generating electricity.
How do you get energy in a useful form from coal?
By burning it, which produces heat
