Dispersing a thing full of energy (7)
I believe the answer is:
heating
'dispersing a thing full of energy' is the definition.
I can't judge whether this definition defines the answer.
'dispersing a thing full of energy' is the wordplay.
'dispersing' indicates anagramming the letters.
'full of' means one lot of letters goes inside another.
'energy' becomes 'e' (physics symbol as in E=mc2).
'a'+'thing'='athing'
'athing' with letters rearranged gives 'hating'.
'hating' placed around 'e' is 'HEATING'.
Can you help me to learn more?
(Other definitions for heating that I've seen before include "Rising in temperature" , "can this be provided centrally?" , "Warming" .)
