In any heat engine there is always some rejection of heat to the environment. Thus an internal combustion engine, as in a car, rejects heat in its exhaust gases, and also loses heat into its radiator. An aircraft jet engine rejects heat at its exhaust, it is impractical to extract more energy from this. In a power plant the steam turbine rejects heat to its condenser in order to condense the exhaust steam to water for feeding back to the boilers.
Yes, a given amount of mechanical energy can be converted into heat energy through processes like friction or resistance. In these processes, some of the mechanical energy is lost due to the generation of heat.
Yes, use a Flamethrower or Grenade.

The first law of thermodynamics is an expression of the law of conservation of energy and identifies heat transfer as a form of energy transfer. The second law limits the efficiency of engines. While mechanical energy can always be converted entirely into heat, heat cannot be converted entirely into mechanical energy. Attempts to convert heat completely into energy always produce some waste heat.
Yes. In fact, sooner or later, it usually WILL be converted to heat energy. Converting energy the other way is not possible - if you have a given amount of heat energy, you might convert part of it to mechanical energy under certain circumstances, but never all of it.
No, most heat energy can never be converted into work. Heat is the most entropic form of energy, and therefore is limited by the second law of thermodynamics.
Yes, examples are steam turbines, locomotive, hydraulic turbines, etc.

What is a wasted form of energy given out by a hairdryer?
Heat energy is a wasted form of energy given out by a hairdryer. A significant amount of the electricity consumed by a hairdryer is converted into heat to dry the hair, making it an inefficient use of energy.
Is it possible to entirely convert a given amount of heat into mechanical energy?
No, it is not possible to entirely convert a given amount of heat into mechanical energy due to inefficiencies and losses in the conversion process, as described by the second law of thermodynamics. Some heat will always be lost to the surroundings as a byproduct during the conversion process.
The energy produced when 1kg of a substance is fully converted into enetgy is?
The energy produced when 1kg of a substance is fully converted into energy is given by Einstein's famous equation E=mc^2, where E is the energy produced, m is the mass of the substance (1kg in this case), and c is the speed of light. This equation shows that a large amount of energy can be generated from a small amount of mass.
How does the amount of energy in the batteries compare to the total amount of light given off by the flashlight?
The amount of energy stored in the batteries is typically higher than the total amount of light output by the flashlight, as some energy is lost as heat during the conversion process. The efficiency of the flashlight will determine how much of the stored energy is actually converted into light.
What type of energy conversions occur when energy is given off by splitting atoms turn into water steam?
When energy is given off by splitting atoms, it is converted from nuclear energy to thermal energy. This thermal energy is then used to heat water and turn it into steam, which can be used to drive turbines and generate electrical energy, converting the thermal energy into mechanical and then electrical energy.
Is it possible to totally convert a given amount of mechanical energy into heat?
Strictly speaking, it's not. It's connected to the fact that the mechanical energy can be converted to IR radiation (or other kinds of EM waves), or it can be converted to the vibrations of the material's lattice and so on.

Can you convert a given heat energy into mechanical energy?
yes you can

The amount of chemical energy in consumers' food that is converted to their own new biomass during a given time period is known as?
The amount of chemical energy in consumers' food that is converted to their own new biomass during a given time period is known as Net Primary Productivity (NPP). It represents the energy that is available to the next trophic level in an ecosystem for growth and reproduction.
The energy produced when 1kg of a substance is fully converted into enetgy is?
The energy produced when 1kg of a substance is fully converted into energy is given by Einstein's famous equation E=mc^2, where E is the energy produced, m is the mass of the substance (1kg in this case), and c is the speed of light. This equation shows that a large amount of energy can be generated from a small amount of mass.
What term is the amount of biomass produced in a given area?
The term for the amount of biomass produced in a given area is "primary productivity." It refers to the rate at which energy is converted into organic substances by autotrophic organisms through photosynthesis or chemosynthesis.

Energy that is not converted to useful energy is usually given off as?
Waste heat.
Does an electric generator motion produces magnetism or power or electricity?
An electric generator converts mechanical energy into electrical energy. When the generator's motion rotates the magnetic field around conductive coils, it induces a flow of electrons, creating an electric current. This current is the electricity produced by the generator.
What is most energy given off as?
Most energy is given off as heat, which is a form of energy that is transferred from one object to another due to a difference in temperature. When energy is transferred or converted from one form to another, some amount of energy is usually lost as heat.
