  • Science -

    radiation and conduction are not chemical changes.

    One chemical change is combustion,fuel is burning in air to produce heat, carbon dioxide and water.

    The other chemical change is in the bbq itself. Heat is breaking down the protein bonds in the meat to make it tender, and shorter length protein chains which are tender.
