They plan exploitation of body heat? (8)

Ross

I believe the answer is:

enthalpy

I'm a little stuck... Click here to teach me more about this clue!

'body heat?' is the definition.
The definition and answer can be both human attributes as well as being singular nouns.
Perhaps you can see a link between them that I can't see?

'they plan exploitation' is the wordplay.
'they plan' can be anagrammed to 'ENTHALPY'.
However, I'm not sure how this is indicated.

'of' acts as a link.

Can you help me to learn more?

(Other definitions for enthalpy that I've seen before include "Thermodynamic measure of total heat content" , "Measure of energy" , "Total heat content of a system" , "Function for physical chemists" , "Thermodynamic quantity" .)

I've seen this clue in the Sydney Morning Herald.
