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

    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).
