Physical and chemical changes 1.) melting of max 2.)baking of bread​

Answer 1

Baking of bread and melting of wax both r physical changes

Answer 2

Answer:

Physical changes don't destroy your sample or make it into something new.

Physical changes change the shape, size or phase of a substance. Crumpling paper, getting a haircut, dissolving salt in water, melting wax, making ice cubes, chopping veggies for tossed salad, growing crystals from a supersaturated solution, grinding metal and slicing bread are all physical changes.

During a physical change the elements and compounds stay as they are.

Chemical changes make new substances. Cooking an egg rearranges it's proteins. Burning fuels, etching metal with an acid, fermentation, respiration in your cells, decomposition in the compost pile, making zinc iodide in the lab, and forming a silver mirror are all chemical changes.

During a chemical change the elements and compounds get rearranged and recombined into something new.
