Convert Internal Energy to Mechanical Energy: Real Life Examples

[qasimdada]

is it possible to convert internal energy into mechanical energy? is there some real life example which can explain this?

 

[dx]

What kind of internal energy? By mechanical energy, do you mean work? For example, thermal energy can be converted into work, but there are limits due entropy.

Yes, there is a rather famous example of this... a steam engine. Heat causes the water to turn to steam and the rising of the steam turns a turbine (and that turbine, in turn could be attached to a dynamo motor to produce electricity). Voila, usable energy from heat (although the efficiency of such processes suck).
