*’heat engines’ burn a fuel to create ‘heat’, which is then used to create a ‘force’*
.
(in ‘thermodynamics’, a heat engine is a system that converts ‘heat’ (or ‘thermal energy’) + ‘chemical energy’ –> ‘mechanical energy’, which can then be used to do ‘mechanical work’)
(it does this by bringing a ‘working substance’ from a ‘higher state temperature’ to a ‘lower state temperature’)
(a heat “source” generates ‘thermal energy’ that brings the ‘working substance’ to the ‘high temperature state’)
(the ‘working substance’ generates ‘work’ in the “working body” of the ‘engine’ while transferring ‘heat’ to the colder ‘sink’ until it reaches a ‘low temperature state’)
(during this process, some of the ‘thermal energy’ is converted into ‘work’ by exploiting the properties of the ‘working substance’)
(the ‘working substance’ can be any ‘system’ with a ‘non-zero heat capacity’, but it usually is a ‘gas’ or ‘liquid’)
(during this process, a lot of ‘heat’ is lost to the ‘surroundings’)
(meaning it cannot be ‘used’)
(in general, an ‘engine’ converts ‘energy’ to ‘mechanical work’)
.
(‘heat engines’ distinguish themselves from other types of ‘engines’ by the fact that their ‘efficiency’ is fundamentally limited by ‘carnot’s theorem’)
(although this ‘efficiency limitation’ can be a ‘drawback’, an advantage of ‘heat engines’ is that most forms of ‘energy’ can be easily converted to ‘heat’ by processes like…)
*’exothermic reactions’*
(such as ‘combustion’)
*absorption of ‘light’ (or ‘energetic particles’)*
*friction*
*dissipation*
*resistance*
.
(since the ‘heat source’ that supplies ‘thermal energy’ to the ‘engine’ can thus be powered by virtually any kind of ‘energy’, ‘heat engines’ are very ‘versatile’ and have a wide range of ‘applicability’)
(‘heat engines’ are often confused with the ‘cycles’ they attempt to implement)
(typically, the term ‘engine’ is used for a ‘physical device’ and ‘cycle’ for the model)
