What device can convert heat to machinical energy?
A device that converts heat to mechanical energy is called a heat engine. Heat engines operate by using thermal energy from a heat source to perform work, usually through a cyclic process involving the expansion and contraction of gases or fluids. Common examples include steam engines and internal combustion engines, which harness heat from fuel combustion to produce mechanical power.
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.
How do heat engines use heat to do mechanical work?
Heat engines convert thermal energy into mechanical work by utilizing the principles of thermodynamics. They absorb heat from a high-temperature source, which causes a working fluid (like steam or gas) to expand and perform work, typically by moving a piston. As the fluid expands, it does work on the surroundings, and then it releases some heat to a lower-temperature sink before being compressed to repeat the cycle. This continuous process allows the engine to convert a portion of the absorbed heat energy into useful mechanical work.
WHAT IS expansion stroke?
The expansion stroke is a phase in the four-stroke engine cycle where the combustion gases expand, pushing the piston down in the cylinder. This occurs after the power stroke, where the fuel-air mixture has been ignited. During this stroke, the piston moves from the top dead center to the bottom dead center, converting thermal energy from combustion into mechanical energy. This process is essential for generating the power needed to drive the engine.
What is the Significance of brake thermal efficiency?

What is a device that converts thermal energy into work?
A device that converts thermal energy into work is called a heat engine. Heat engines take thermal energy from a heat source, such as combustion or nuclear reactions, and convert it into mechanical work through processes like expansion of gases or steam. Examples include steam engines and internal combustion engines.
What is device that transforms thermal energy to mechanical energy?
Steam engine is a device that transforms thermal energy into mechanical energy. An internal combustion engine (I.C Engine) can transform thermal energy into mechanical energy. In nuclear power plant also the heat energy released is used to turn the turbine and thus thermal energy is converted into mechanical energy of rotation of turbine. This mechanical energy of turbine is further converted into electrical energy in generator.
What is a device that changes thermal energy into mechanical energy?
Heat engines like your lawn mover or car a combustion engine.
What energy transformation takes place in an engine?
In steam and combustion engines, thermal energy is changed to mechanical energy. Either heated gas or heated fluid is created that exerts force to turn the engine. In combustion engines, chemical energy becomes thermal energy which becomes mechanical energy. In electrical engines (motors), electrical energy is changed to mechanical energy by the manipulation of magnetic fields.

What does thermal energy convert to?
Thermal energy can be converted into other forms of energy, such as mechanical, electrical, or chemical energy. This conversion can occur through processes like heat engines, thermoelectric generators, or chemical reactions. The specific method of conversion depends on the desired end-use of the energy.
