Quantum Field theory states that if you supply energy particles should emerge. Supposing I heat a system so that it glows red hot.So obviously photons are being created-- so in supplying energy to a quantum field-- we are in fact getting particles which are created as a result of supplying energy.
So if the above statement is true then heat energy is being converted to electrical or light energy-- ( photons)
So-- IS THIS THE BASIC MECHANISM FOR CONVERSION OF ENERGY-- ENERGY CANNOT BE CREATED OR DESTROYED-- ONLY CONVERTED ?
So when heat is supplied to fermions -- bosonic particles are created-- thus converting energy.
Is this the QFT interpretation for conversion of energy?
