How Much Heat Cannot Be Converted to Work?
The second law of thermodynamics can be expressed as the following: It is impossible in any system for heat transfer from a reservoir to completely convert to work in a cyclical process in which the system returns to its initial state.

In which process heat is fully converted into work?

In a process like ideal (neglecting friction) isothermal expansion of a piston (only the expansion is considered), the heat you apply is completely converted into work.

Can all heat be converted into work?

Work is the transfer of energy by any process other than heat. Heat and work are related: work can be completely converted into heat, but the reverse is not true: heat cannot be completely converted to work.
