Work done is used as a term to communicate that a predetermined task has been completed OR to specifify a percentage of the task completed by saying that work done is at (f.i.) 70%
Water is heated to produce steam. The steam is used to power the engine. The power from the engine does the work or powers other instruments that do the work.
thermodynamics, is essential for mechanical engineers, because the subject is mainly about heat and work in system, and as an engineer that is important, especially when you have to design engines, because that is when you have to determine important factors such as the amount of work that can be done by that engine internally, and the heat it transefered and obtained.

An engine is a motor that converts thermal energy to mechanical work.
The amount of work done by a heat engine equals the difference between the heat input and the heat output of the engine. This is known as the heat engine's thermal efficiency.
the steam engine was quicker and stronger than hoses
steam engine was quicker than horses and stronger than horses
Work done=Heat in-Heat out 2000-1500=500J
Yes. The work is being done by whoever is pushing rather then the engine, but work is being done. Any time a force is applied through a distance, work is being done.
You take one engine out of a car and put another one in. Done.
steam engine was quicker than horses and stronger than horses
No work is being done by the automobile if it is standing still with the engine running since it isn't in motion (not counting any work done by the vibrations transmitted to the air and ground upon which it rests). The engine, on the other hand IS doing work while idling since the parts inside are moving and both having work done on them and, in turn, performing work on other parts.
The amount of work done by a heat engine is not equal to the amount of thermal energy it absorbs. In a heat engine, only a fraction of the thermal energy absorbed is converted into work, with the remaining energy typically being expelled as waste heat. The efficiency of a heat engine is a measure of how effectively it converts thermal energy into work.
The amount of work done on an automobile by its engine is directly related to the energy content of the gasoline used as fuel. Gasoline contains potential energy stored in its chemical bonds, which is released during combustion in the engine to produce work that moves the vehicle. The higher the energy content of the gasoline, the more work can be done by the engine.
If you do all the work yourself, it can be done for a couple hundred dollars.
The amount of work done by a heat engine is equal to the difference between the heat input and the heat output. This is based on the first law of thermodynamics, which states that energy cannot be created or destroyed, only transformed. In a heat engine, this transformation occurs from thermal energy to mechanical work.
