Fire expends ENERGY which is a by-product of conversion of matter.

The calories or therms of a fire equal a certain amount of mass.

When MATTER (Electron) and ANTI-MATTER (Positron) collide they don't inhillate each other with nothingness, they always realse TWO gamma particles.

The ENERGY of the TWO gamma particles CONSERVES the MASS of the ELECTRON and The POSITRON
