Is old ham in the refrigerator a chemical change or physical change?

Answer 1

When ham get "old" (ie rots or degrades), it undergoes both a chemical and a physical change. Microbes break down the meat into energy they can use and in turn leave their metabolic wastes (ie a biochemical change). When a person notices a ham after it has been sitting on a shelf for several week, that person will notice that the color, shape, smell, and taste (if they are brave) of the ham has changed. Thus the changes are both chemical and physical
