No engine is 100% efficient: there is always some loss of energy between input and output.

What is the heat engine?
A heat engine is a system that converts heat to usable energy, particularly mechanical energy, which can then be used to do mechanical work
How do you convert heat energy to mechanical?
In some refrigeration systems, mechanical energy is converted to heat energy by mechanically compressing a refrigerant, by means of a compressor; and since refrigerants have a fixed pressure-temperature relationship, much like saturated steam, altering the pressure of a refrigerant correspondingly alters its temperature. I've read of other methods utilizing friction, which is itself mechanical energy in the more pure and direct sense rather than the operation of a mechanical device which itself is utilizing electrical energy, but the compressor example is the only practical real-world application of this nature in common, everyday use that I can think of.
What is the Significance of brake thermal efficiency?
It is used to evaluate how efficient an engine converts the heat from a fuel to mechanical energy.
What is the motor that converts thermal energy to mechanical energy?
The generic term is "heat engine". Most engines - for example, car engines - are in this category.
What are stirling engines used for?
Stirling engines convert heat into mechanical movement. See the related link to Wikipedia, which has not only a detailed discussion of the subject, but also a nice animation.
How do you convert thermal energy to mechanical energy?
heat engine
What is the use of steam engine?
To convert heat energy into mechanical work.
What is the steam engine's function?
To convert heat energy into mechanical energy.
Can you convert mechanical energy to heat energy?
Absolutely a simple example is the engine.
How do you convert chemical to mechanical?
Chemical energy can be converted to mechanical energy by harnessing the energy released during a chemical reaction. This can be achieved using various methods, such as combustion engines, where the chemical energy in fuel is converted into heat energy and then mechanical energy to power vehicles. Alternatively, chemical-to-mechanical energy conversion can also occur in processes like battery-operated devices where chemical reactions inside the battery generate electrical energy, which is then converted into mechanical energy to perform tasks.
Can a heat engine converts disordered mechanical motion into organized mechanical motion?
Yes, a heat engine can convert disordered thermal energy into organized mechanical motion by utilizing the principles of thermodynamics through processes such as combustion or steam production. This organized mechanical motion can then be used to perform useful work.
What is the difference between internal combustion engine and heat engine?
An internal combustion engine is a type of heat engine that generates mechanical energy by burning fuel inside the engine. A heat engine, on the other hand, is a broader category of engines that convert heat energy into mechanical work through various processes, including combustion, thermodynamic cycles, and heat transfer. In essence, all internal combustion engines are heat engines, but not all heat engines are internal combustion engines.
What is a device that uses heat to do work and but is not 100 percent efficient and expels excess heat?
A common device that fits this description is a combustion engine, such as those found in cars. These engines convert the heat generated from burning fuel into mechanical energy to do work, but they are not 100% efficient and expel excess heat through the exhaust system.
Heat engines are devices that convert thermal energy into?
mechanical engergy
Is it possible to convert internal energy to mechanical energy?
Yes, examples are steam turbines, locomotive, hydraulic turbines, etc.
What is used to convert heat into mechanical energy?
Turbines
What does a heat engine convert heat in to?
A heat engine converts heat energy into mechanical work, usually in the form of rotating a shaft or driving a piston. This process is governed by the laws of thermodynamics, specifically the conversion of heat into work through the expansion and compression of a working fluid such as steam or gas.
