No, due to the second law of thermodynamics, a heat engine cannot convert all of its heat energy into work. Some heat will always be lost to the surroundings, decreasing the efficiency of the process.
False (APEX)
A heat engine converts heat energy into mechanical work, usually in the form of rotating a shaft or driving a piston. This process is governed by the laws of thermodynamics, specifically the conversion of heat into work through the expansion and compression of a working fluid such as steam or gas.
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.
One way to work with heat energy is to convert it into mechanical energy using a heat engine, such as a steam engine or gas turbine. Another method is to transfer heat energy using a heat exchanger to heat or cool a substance or space. Additionally, heat energy can be converted into electricity using thermoelectric generators or solar panels.

To convert heat energy into mechanical work.
Yes - with certain limitations. You can convert part of the heat - not all of the heat - into useful work, if there is a heat difference. The remainder of the heat (from the hot container) gets passed to the cold container. You CANNOT convert ALL the heat into useful work, nor can you convert heat into useful work if there is no heat difference. All this would contradict the Second Law of Thermodynamics, and it is very unlikely that this law will ever be violated.
False its not possible to convert all heat into work as some of its being used as energy APEX

No engine is 100% efficient: there is always some loss of energy between input and output.
work
No, a heat engine is not a device that converts work into heat. It is the opposite, which means it is a device that converts heat into 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.
