Melting

Melting is a purely physical change because the solid object is becoming a liquid. During this process nothing is lost or exchanged.

Tarnishing and rusting is a purely chemical change where the make-up of an object is changing through oxidization, therefore creating an exchange.

Burning is a chemical and physical change because the object is changing on a chemical level as it burns and there is a loss of mass when the burning results in the vaporization of material.
