the claim

Heat can be completely converted into mechanical work.

the verdict
CONTESTED PARTIAL
Recorded sources
2 sources for · 2 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that heat can be completely converted into mechanical work?

Partly. A physics discussion and a heat-engine reference indicate heat cannot be fully converted to work in practical cyclic processes, while a set of papers on correlated quantum particles describe complete heat-to-work conversion only in a special idealized setup. Neither side settles the general claim as worded.
